"[Social Justice Campaigners] decided instead to push vigorously on trans: to pick up the hardest part of the whole question ('I am who I say I am and you can't prove otherwise') and run with it: 'Trans lives matter'; 'Some people are trans. Get over it'. Everywhere, with a wearying predictability, the people who always complain about every aspect of the patriarchal, hegemonic, cis-supremacist, homophobic, institutionally racist, sexist state, decided to run with the trans issue. They specifically claimed that yes, if a man said he was a woman and didn't do anything about it, then yes he was a woman and it was transphobic to suggest otherwise."
