Kathleen Stock was until last week a professor of philosophy at the University of Sussex. In the last few years she has become better known for her gender critical views, contributing to the highly charged public debate over trans rights and what she and others see as the re-defining of the word ‘woman’. This year she published a book called Material Girls: Why Reality Matters for Feminism, in which she argues that we are in an era of Emperor’s New Clothes, that it isn’t possible for people to change their biological sex, and that someone’s sex should sometimes takes precedence over their gender identity. She is also clear that “Trans people deserve lives free from fear. They deserve laws and policies that properly protect them from discrimination and violence. But as she says…laws and policies based around gender identity are not the right route.” She gives an exclusive interview to Emma Barnett.
