Overview

Gender-critical feminism (often shortened to GC) is a strand of feminist thought and activism holding that biological sex is real, binary and unchangeable, that it matters for women's rights, and that a person's gender identity (an inner sense of being a man, a woman, both or neither) should not replace sex in law, policy, language or data. Its name comes from its central claim: "gender", meaning the social roles and stereotypes attached to each sex, is something to criticise and ideally abolish, not something people are born with.

The movement became a major political force in the United Kingdom after 2017, when the government consulted on letting people change their legal sex by self-declaration. Since then it has won landmark court cases, built a network of campaign groups and spread to other countries. It is also one of the most bitterly contested movements of recent years. Its opponents, including many trans people and many other feminists, describe it as an anti-trans movement and often call its supporters TERFs (trans-exclusionary radical feminists).

This page sets out what gender-critical feminists believe, where the movement came from, what it has achieved in law, the dispute over the word "TERF", the strongest criticisms made of it, and how detransitioners relate to it. That relationship is complicated: some credit gender-critical ideas with helping them understand their transition, while others feel used by the movement. For the wider history, see feminism and its fourth wave, where the split over trans inclusion is a defining story.

What "gender-critical" means

The phrase describes a particular analysis of gender rather than a membership. One /r/detrans commenter summed up the two parts often used to define it:

1. Anyone who opposes the system of gender (which necessarily includes the current social and political forces seeking to reify it) and 2. opposes the prioritization of gender identity over sex in language, law and public policy is gender critical. It describes a particular analysis of gender. —drt007, detrans

The first part is philosophical: gender is understood as a set of expectations imposed on people because of their sex, not as an inner identity. The second is political: in conflicts between sex and gender identity, sex should prevail where the law or a policy is meant to protect women as a sex class. The second claim is the one that drives most public campaigning, and it can be held by people who do not share the first. That gap explains much of the movement's internal tension.

Relationship to radical feminism

Gender-critical feminism grew out of radical feminism, the strand of second-wave feminism that sees male dominance over women (patriarchy) as the root social hierarchy and gender roles as its tool. Writers such as Andrea Dworkin argued for abolishing gender altogether, and Janice Raymond's The Transsexual Empire (1979) applied a radical-feminist critique to medical transition. Raymond's book remains a key point of reference for both supporters and critics (Serano 2024).

But the two terms are not the same, and many people on both sides insist on the difference:

• Radical feminism is a broad theory about patriarchy, covering pornography, prostitution, male violence, reproduction and much else. Some radical feminists are trans-inclusive.
• Gender-critical campaigning focuses on sex and gender identity, especially law and policy. Many people who campaign on these issues do not share radical feminism's wider politics, and some are politically conservative.

Commenters in r/detrans make the same distinction from inside the debate:

a lot of gender critical women aren't really radical feminists at all, they just dislike trans ideology. —quoted in a 2021 r/detrans thread asking whether others felt "betrayed or used by radfems" (account since deleted)

Some trans critics read this broadening as the movement's main change. Trans writer Julia Serano dates the first use of the label "gender critical" to the founding of the r/GenderCritical forum on Reddit in September 2013. She argues that the switch from "radical feminist" to "gender critical" marked a shift from a small feminist faction to a broader coalition united mainly by opposition to trans rights (Serano 2024, trans advocate). Gender-critical writers usually describe the same broadening as ordinary women who are not feminist theorists becoming concerned about practical questions.

Core claims

Gender-critical positions vary, but these claims come up again and again in the movement's books, campaigns and legal arguments:

• Sex is real, binary and immutable. Humans are male or female, and no medical or legal process changes that. Differences of sex development are treated as variations within the two sexes, not as evidence of a spectrum.
• Sex matters for women's rights. Women's oppression, from pregnancy discrimination to sexual violence, is rooted in their sex, so laws protecting women need a sex-based definition of "woman".
• Gender identity should not override sex in law and policy. This was the core of the opposition to "self-ID" (changing legal sex by declaration alone).
• Single-sex spaces. Changing rooms, toilets, refuges, rape crisis services, hospital wards and prisons should be separated by sex where privacy, dignity or safety is at stake.
• Sport. Female sports categories should be limited to females because of male physical advantages.
• Data. Official statistics, medical records and research should record sex accurately, and record gender identity separately if at all.
• Language. Opposition to replacing "woman" with terms like "people with a cervix", and to compelled use of preferred pronouns.
• Children and young people. Concern about social and medical transition of minors, and about lesbian, gay and gender non-conforming youth being steered towards transition. This last concern is where the movement overlaps most directly with detransitioners.

Leading statements of these views include philosopher Kathleen Stock's Material Girls: Why Reality Matters for Feminism (Stock 2021, Fleet) and journalist Helen Joyce's Trans: When Ideology Meets Reality (Joyce 2021, Oneworld). These claims connect to the wider debate covered in sex vs gender in law.

Many gender-critical people say they support legal protections for trans people in housing, work and healthcare while opposing self-ID. One detransitioner described that position:

I still believe that trans people deserve equal rights in housing, employment, and access to medical care. I just no longer believe that medical transition is life-saving treatment; I think that lots of homosexual and gender non-conforming people are pressured to transition… —lunitabonita

Critics answer that a "right" to housing or work means little if trans women are legally treated as men in every women-only setting. That disagreement over what counts as "rights" runs through the whole debate.

Origins in the UK

The Gender Recognition Act consultation (2017–2018)

Under the Gender Recognition Act 2004 (GRA), people in the UK can change their legal sex by getting a Gender Recognition Certificate (GRC), but only with a medical diagnosis of gender dysphoria and evidence of living in their "acquired gender" for two years. In 2017 Theresa May's government proposed reforming this, and in July 2018 it opened a public consultation on England and Wales that included a self-declaration option. It closed on 22 October 2018 (House of Commons Library 2024).

The consultation acted as a catalyst. Women who had worried privately about self-ID began organising in public, arguing it would open women-only spaces to any man who declared himself a woman. In September 2020 the government dropped self-ID, even though most consultation responses supported reform (Wareham 2020, Forbes). Gender-critical campaigners counted this as their first major victory. Trans organisations saw it as a betrayal.

In Scotland a separate reform, the Gender Recognition Reform (Scotland) Bill, passed the Scottish Parliament in December 2022. The UK government blocked it in January 2023 using section 35 of the Scotland Act, and the Court of Session upheld the block in December 2023 (Judiciary of Scotland 2023). See the UK law page for detail.

Mumsnet and online organising

Much early organising happened online, above all on Mumsnet, a large British parenting forum. Its feminism boards became a hub for gender-critical discussion from around 2016. A critical 2018 Vice investigation reported claims that trans topics dominated the board and that the site tolerated misgendering and attacks on trans activists. Mumsnet's founder defended its free-speech policy (Vice 2018). Supporters saw it as one of the few mainstream spaces where women could discuss these questions; critics saw an engine of transphobia.

Campaign groups

A cluster of organisations formed or grew in this period. All of them are advocacy groups, and their own descriptions of their aims should be read as such:

• Woman's Place UK (WPUK): founded on 22 September 2017 by women from trade unions and social movements in response to the GRA proposals (WPUK 2024, advocacy).
• Fair Play for Women: campaigned against self-ID and on sport (Cosmopolitan 2019).
• LGB Alliance: founded in 2019 in opposition to Stonewall's trans policies, arguing that same-sex attraction is defined by sex. A tribunal rejected a Mermaids-led challenge to its charitable status (Charity Times 2023). Critics call it an anti-trans lobby group (PinkNews 2022).
• Sex Matters: founded in 2021 by Maya Forstater and others, now a registered charity campaigning on sex in law, data and policy (Sex Matters, advocacy).
• FiLiA: a feminist charity whose annual conference centres sex-based rights; its 2025 Brighton conference drew more than 2,400 delegates and protests (The Argus 2025).
• For Women Scotland: the Scottish campaign group whose litigation reached the Supreme Court (below).

Author J.K. Rowling's June 2020 essay on her reasons for speaking out, in which she disclosed her own experience of domestic abuse and sexual assault, brought the debate to a global audience (Brooks 2020, Guardian).

Key legal moments

Three rulings define the movement's legal record in Britain, with further disputes still in the courts.

The appeal tribunal in Forstater (2021) held that the belief that sex is real, important, immutable and not to be conflated with gender identity is protected under the Equality Act 2010 and Article 9 of the European Convention on Human Rights, while stressing that it expressed no view on the merits of either side (Old Square Chambers 2021; JMW Solicitors). Later belief cases, such as Allison Bailey's, built on it (Crossland Solicitors).

In For Women Scotland (16 April 2025) the Supreme Court ruled unanimously that "woman" and "sex" in the Equality Act mean biological sex, so a trans woman with a GRC is not a "woman" for that Act's purposes (Kennedys 2025). Lord Hodge warned against reading it "as a triumph of one or more groups in our society at the expense of another", noting that trans people remain protected from discrimination (Sky News 2025). Critics argued the ruling was unworkable and set trans women against other women (Völkerrechtsblog 2025). The Equality and Human Rights Commission (EHRC), Britain's equality regulator, then revised its services code, which became statutory on 5 August 2026 with guidance on single-sex services (EHRC 2026).

On data, a government-commissioned review led by sociologist Alice Sullivan (2025) found a "widespread loss" of sex data and recommended recording sex by default (UCL 2025; Times Higher Education); LGBTQ+ groups called it biased (PinkNews 2025). Full detail is on the UK law page.

Academic disputes

Universities became a flashpoint. Philosopher Kathleen Stock was made an OBE in 2020; more than 600 philosophers signed a letter criticising the honour, while others signed letters defending her academic freedom (PinkNews 2021; Legal Cheek 2021). After a student campaign for her dismissal she resigned from the University of Sussex in October 2021 (New Statesman 2021). In March 2025 the Office for Students (OfS), England's higher education regulator, fined Sussex a record £585,000, finding that its trans equality policy statement, which required staff and students to "positively represent" trans people, risked a "chilling effect" (PinkNews 2025; Wonkhe 2025). The university said it would challenge the fine, and Universities UK warned it complicated efforts to prevent harassment (Guardian 2025).

The same divide runs through scholarship. The Sociological Review monograph TERF Wars (2020) gathered trans-inclusive feminist scholars who argued that gender-critical claims rest on "moral panic" and misinformation (Pearce, Erikainen & Vincent 2020). The fight over how these debates are described extends to online reference works: Wikipedia titles its main article on the movement "Trans-exclusionary radical feminism" rather than using the movement's own name, a framing gender-critical scholars reject.

International spread

Gender-critical feminism is strongest in the UK, but it has an international network and local variants:

• United States. The Women's Liberation Front (WoLF), a radical-feminist group, has opposed gender-identity provisions in federal law. In January 2019 three WoLF members spoke on a Heritage Foundation panel opposing the Equality Act, a collaboration critics called an "unholy alliance" with the religious right (Advocate 2019; Ms. 2019). See the US law page.
• United Nations. The UN Special Rapporteur on violence against women and girls, Reem Alsalem, reported in October 2024 that more than 600 female athletes had lost more than 890 medals to male competitors, and called for sex-based categories in sport (OHCHR 2024; Sex Matters, advocacy).
• Spain. The 2023 "Ley Trans", which allows legal gender change by declaration from age 16, split the feminist movement and the governing Socialist party. Former deputy prime minister Carmen Calvo, a veteran feminist, abstained and was fined by her party (BBC 2022; El Confidencial 2023). See Europe.
• Australia. In Tickle v Giggle (2024), the Federal Court found that a women-only app had unlawfully discriminated against a trans woman by excluding her. An appeal court upheld and expanded the ruling in May 2026 (Human Rights Law Centre; Guardian 2026). This is the opposite of the UK outcome.
• South Korea. Self-described radical feminists in online women-only communities have pushed a trans-exclusionary feminism with its own local roots (Feminist Media Studies 2026).

The word "TERF"

Origin

"TERF" stands for trans-exclusionary radical feminist. It is usually credited to Viv Smythe, an Australian trans-inclusive radical feminist, who used it on a blog in 2008. She has described it as a "deliberately technically neutral" shorthand for the minority of radical feminists who excluded trans women, as distinct from trans-inclusive radical feminists like herself (Xtra). In a 2018 Guardian piece she wrote that she has no control over how others now use a word that came about to save typing a phrase over and over (Smythe 2018).

Contested meaning

The case that it is a fair descriptor. Many trans people and their allies say "TERF" accurately names a specific position: feminism that excludes trans women from womanhood. Some argue the "feminist" part is undeserved; others stress that trans-inclusive radical feminism exists, which is exactly why the qualifier "trans-exclusionary" is needed:

the reason they're called TERFs and not RFs is that plenty of trans-inclusive strains of radical feminism also exist —myaltduh, mtf

The case that it is a slur. Gender-critical feminists generally reject the term. They point to its use alongside threats, its application to people who are not radical feminists, and its use to shut down debate. Many detransitioners report being called TERFs simply for detransitioning. A desisted woman who once used the word herself described changing her mind:

TERF doesn't mean anything consistent, it gets used to discredit anyone who says anything supportive of the belief that biological sex matters in certain contexts by lumping them in with the most virulently hateful transphobes. —milleputti, desisted female

A fair reading is that the word does two jobs. Some people use it as a precise label for a political position. Others use it as a broad insult for anyone who disagrees about sex and gender. Which use is at work depends on the speaker and the context. For how the label is used against detransitioners in particular, see backlash against detransitioners.

Critiques of gender-critical feminism

Opposition comes from trans people, trans-rights advocates and many feminists who see trans inclusion as part of feminism. The strongest arguments are summarised here as their proponents make them.

Exclusion and essentialism

Critics argue that defining women by biology reduces womanhood to reproduction, which feminism has long opposed, and that it excludes trans women who face misogyny and transphobia together. Some trans commenters argue that gender-critical thinking is itself a form of biological essentialism:

Radical feminism is antithetical to real feminism because it roots itself in bioessentialism. You cannot embrace transness and bioessentialism at the same time, it's a contradiction. —Emotional_Tomato_, ftm

Others say the movement's emphasis on women's vulnerability is itself old-fashioned:

The idea that women must be "protected" plays into gender stereotypes of women as weak and fragile. —GrayCatbird7, MTF

Gender-critical writers reply that recognising sex is not the same as essentialism about behaviour. Their whole argument is that sex is a bodily fact and personality is not dictated by it. This is why many detransitioners say GC ideas freed them from stereotypes rather than trapping them (see below).

Alignment with the political right

The most damaging criticism is that the movement has made alliances with, or given cover to, the political right, including groups opposed to abortion and LGB rights. Critics point to:

• WoLF's 2019 Heritage Foundation panel and its work with conservative legal groups (Advocate 2019).
• A "Let Women Speak" rally in Melbourne in March 2023 organised by British activist Kellie-Jay Keen-Minshull, where a group of neo-Nazis appeared and performed Nazi salutes (GNET 2023). Critics cite it as evidence that the wider campaign attracts the far right; supporters reject this as guilt by association.
• Philosopher Judith Butler's argument in Who's Afraid of Gender? (2024) that "gender critical" feminists have formed an unconscious alliance with an authoritarian, global "anti-gender" movement (El País 2024). See queer theory.

Gender-critical feminists respond that agreeing with conservatives on one issue is not an alliance, that left-wing parties left them politically homeless, and that many in the movement are socialists and lesbians. Some commenters in r/detrans make the same point:

These radical feminist ideas are really as left as it gets, so I don't like this misconception that anything not pro-trans is right wing. —Many-Brilliant-192, detrans male

Both things can be true at once. Many gender-critical feminists are on the left, and one desisted woman pointed out that the religious right is not "fighting for abortion, criticising gender roles, criticising the unpaid labour of women". At the same time, some gender-critical organisations have worked with right-wing groups on shared goals, and right-wing politicians have adopted the movement's language.

Harm to trans people

Critics argue that the tone of the UK debate, much of it driven by gender-critical campaigning, has made trans people's lives worse. In October 2023 the Home Office reported a record 4,732 transgender hate crimes in England and Wales for the year to March 2023, an 11% rise. It suggested the rise may have been linked to increased public discussion of "transgender issues", including comments by politicians and the media (BBC 2023; Guardian 2023). By the year to March 2026, recorded transgender hate crimes had fallen by 4% (Home Office 2026). Police-recorded figures cannot show what caused any change.

Some trans commenters see the movement's rhetoric as a modern version of earlier panics:

Usually what they mean is "I want to protect woman from trans-people" (the transphobia part hiding as feminism) —Norththelaughingfox, MTF

Gender-critical campaigners reply that the harms they are trying to prevent are real too: to women in single-sex spaces, to female athletes, and to young people (including future detransitioners) given irreversible treatment. They also point out that gender-critical women have faced threats, harassment and job losses, as several of the tribunal cases above found. On this site's view, the most serious and best-documented harm is permanent medical intervention done without fully informed consent. That is a different claim from saying every gender-critical argument is right.

Gender-critical feminism and detransitioners

Support and amplification

Detransitioners have played a large role in the movement's story, and vice versa. Some gender-critical campaigners were among the earliest public voices to take detransitioners seriously, at a time when detransitioners say they were widely dismissed. In the UK, gender-critical campaigners were prominent supporters of Keira Bell, a detransitioned woman who challenged the prescription of puberty blockers to under-16s; her High Court win was overturned on appeal in 2021 (Guardian 2021). Some detransitioners found that gender-critical forums were the only places that did not ban them for describing regret, a point one detransitioned lesbian made after being banned from a lesbian subreddit.

The "political props" concern

The same relationship raises a recurring worry: that detransitioners are valued mainly as evidence in someone else's argument. Critics of the movement have made this case sharply. A former detransition activist who later re-identified as trans told Refinery29 in 2021 that gender-critical campaigners had drawn in vulnerable, traumatised people to use their stories against trans people (Refinery29 2021). Trans-inclusive scholars argue that detransitioners are framed as "canaries in the gender coal mine", and that research should focus on detransitioners' own needs (Hildebrand-Chupp 2020).

Many detransitioners voice the concern from their own side, often aimed at both political camps at once:

While every anti-trans group/organization/resource only cares about us as much as we can be used as an example of how horrible transition is, and how ruined and mutilated we are after medical transition. —Strange-Gazelle-5697, detrans female

For the full range of this experience, see used as political props.

Detransitioners' views of gender-critical feminism

There is no single detransitioner view of gender-critical feminism. Surveys suggest detransition has many causes (Littman 2021; Vandenbussche 2022). In a qualitative study of six UK women who detransitioned, participants' sense of social belonging often shifted, sometimes alongside feminist values and a new connection with women and lesbian communities (Lomax & Butler 2025). In r/detrans, views range from enthusiastic adoption to firm rejection.

"It gave me a framework"

For many detransitioned and desisted women, radical and gender-critical feminism offered a way to understand their transition as a response to misogyny rather than a sign of being male. A recurring theme is the reframing of gender from an identity into a hierarchy:

Specifically- they were talking about the "gender binary" and stated, "It's not a binary. It's a hierarchy."

And just like that, I saw with absolute clarity- how logically it would follow that FTMs internalized the messages elevating men and denigrating women. —L82Desist, detrans female

Transgender ideology tells you that your body is wrong, radical feminism tells you that society is wrong. —AbolishGender

This links closely to internalised misogyny and internalised homophobia. Some male detransitioners describe a similar effect:

I don't think I could have built the mental framework to get passed my dysphoria without becoming gender critical. —verytiredcatto, detrans male

Psychologically, the appeal is easy to see. Transition locates the problem in the body and offers a bodily fix. A gender-critical reading locates the problem in social expectations, which takes the pressure off the body and allows people to celebrate gender non-conformity without a new label. For some, this is what made healing possible. There is also a risk: swapping one all-explaining framework for another (see gender as an explanatory framework). One commenter recalled that, for her, an earlier period of radical feminism had made her "HATE being female" (comment).

"Hit or miss": criticism from inside

Many detransitioners who agree with gender-critical arguments are critical of gender-critical spaces:

I totally agree with GC arguments and they really helped me during my desisting process, but the groups and the people involved in those communities themselves... it's so hit or miss. —VengefulMufasa, genderfucking female desister

Radfems have unfortunately continued to prove they aren't really allies with their comments and refusal for respect of the delicate situations involving detransition. —DetransIS, Detrans Female with a CCSD

The same commenter added that "rad-leaning people have been the best company" in her own experience, which shows how mixed these feelings can be. Male detransitioners sometimes describe being treated with suspicion:

Because gender critical radfems have a tendency to be very mean to men, and the ones who come here are usually in a bad mental state already. —super-porp-cola, detrans male

Others worry that parts of the online movement have turned against gender non-conforming people, the very group whose freedom it claims to defend:

My sense from Twitter is that an enormous portion of the broader GC community, including both detrans and radfem people, have become pretty GNC-phobic, which has made me feel incredibly alienated from it in recent months. —NeverCrumbling, desisted male

Rejecting the label, or the politics

Some detransitioners reject the gender-critical label altogether, or accept its ideas while refusing any association with the right wing:

I'm all for detrans awareness, and humanizing detransitioners but I refuse to aline myself with right wing politics. —Milokdraws, detrans female

Community splits reflect this too: according to r/detrans users, the alternative subreddit r/actual_detrans does not allow gender-critical views, while r/detrans allows but does not require them (TheDrillKeeper, detrans male). See r/detrans vs r/actual_detrans.

Trans perspectives

Trans people's views of gender-critical feminism are overwhelmingly negative in the communities sampled for this page, though they are not all the same. Some see it as transphobia dressed as feminism. Others draw a line between radical feminism, which they respect, and its trans-exclusionary wing. Some argue that gender-critical arguments land harshly on trans men too, who are cast as "lost" lesbians. One trans woman offered a more hopeful observation from offline life:

TERFs are rare IRL. —tember_sep_venth_ele, mtf

Some trans commenters also see the "detransitioner" label itself as a product of gender-critical campaigning. They argue that "detransition" has always included people pushed back into the closet, and that the public focus on regretful cases serves a political agenda (noeinan, ftm). This page takes the view that trans people who are content with their lives should not be questioned, and that detransitioners' accounts should not be dismissed.

Assessment

Gender-critical feminism has been unusually successful for a grassroots movement. In under a decade it moved from forum threads to the UK Supreme Court and shaped equality guidance across Britain. Its central claims, that sex is real and matters in some legal contexts, are now UK law. Its early willingness to listen to detransitioners, when few others would, deserves credit.

The criticisms are also serious. Some gender-critical organisations have made alliances with right-wing groups whose wider aims conflict with feminism. Some voices in the online movement go well beyond policy disagreement. And the public debate has been painful for trans people, many of whom experience it as an argument about whether they should exist. Detransitioners sit in an awkward spot, valued by one side as evidence and dismissed by the other as a threat. Many commenters in r/detrans say they are tired of being anyone's evidence.

The evidence-led position is to separate the questions. Whether sex should define women-only spaces, sport and data is a question of law and policy. Whether gender is a hierarchy of stereotypes is a question of theory. Whether particular campaigners behave well is a question about people. Gender-critical feminism is right on some of these, contested on others, and no answer to one settles the rest.
