evidence: According to Rowling and other gender-critical activists, women’s safety is highly dependent on dominant gender norms – norms that prevent people with penises, for example, from entering women’s changing rooms and toilets. Transgender people turn those gender norms on their head – and that’s dangerous, according to gender-critical feminists. If anyone can call themselves a woman and just walk into a women’s changing room, penis and all, then it’s only a question of time before rapists start abusing this to assault women. [...] Women’s safety in our society is precarious. 34% of all Dutch women have been victims of sexual violence. In the UK, where JKR is from, one in four women will experience domestic violence, and one in five will experience sexual assault. In fact, Rowling herself is an example of this: in her essay, she writes openly about the abuse she experienced in a previous relationship. But still, are we really going to solve this problem by denying trans women access to women’s toilets? Let’s face it: a symbol on a toilet door is hardly going to stop a rapist with malicious intentions. So, if women’s safety depends entirely on the integrity of sex-segregated spaces, then there’s something seriously wrong with how we’re addressing the problem of sexual violence against women.
