I'm going to defend Jones here. His Corbynism is irritating to me, but I think he deserves credit for his trans rights stuff. One story doing the rounds among the gender critical (I'm using that to mean hardline people, not eg people who see practical difficulties) is that a girl had to leave a school after she was bullied by 60 schoolkids because she asked a question about sex at a lecture on gender.
Jones has tried to ascertain whether this is true. It seems almost too perfect an anecdote, and sources seem a bit thin (and all anonymous). I think he's smart enough, and he'd probably do a decent job tracking this down- I'd rather he did this rather than write columns. He's had a load of horrible shit chucked at him.
