Gender-critical feminism
Gender-critical feminism, also known as trans-exclusionary radical feminism or TERFism, is an ideology or movement that opposes what it refers to as "gender ideology": the concept of gender identity and transgender rights, especially gender self-identification. Gender-critical feminists believe that sex is biological and immutable, while believing gender, including both gender identity and gender roles, to be inherently oppressive. They reject the concept of transgender identities. These views have been described as transphobic by feminist and scholarly critics, and are opposed by many feminist and LGBT rights organizations.
Originating as a fringe movement within radical feminism mainly in the United States, gender-critical views have achieved a degree of prominence in the United Kingdom, where they have been at the centre of a number of high-profile controversies. The Council of Europe has condemned gender-critical ideology, among other ideologies, and linked it to "virulent attacks on the rights of LGBTI people" in Hungary, Poland, Russia, Turkey, the United Kingdom, and other countries. It has been linked to promotion of disinformation and to the anti-gender movement. In some countries, gender-critical feminist groups have formed alliances with right-wing, far-right, and anti-feminist organisations.
