Wouldn't it be better to go armed with the knowledge and self-confidence to put a different point of view? I strongly suspect the vast majority of students do believe there are two sexes and would be open to the idea that gender stereotyping is harmful and GNC people can be just that without having to do anything to their bodies. I'm quite certain most of the staff are. The problem at present is people are frightened of speaking out because it causes so much grief. However, if a student or staff member knew they weren't alone, it would be just that bit easier to say something.
As for Sussex, the presence of Prof Stock on the staff would increase my desire to go there.
Re Goldsmiths - I know it looks like Woke Central from the news coverage, but if you ever pass by in term-time, as I have occasion to do sometimes, it's pretty clear it has a very diverse student body, including lots of local young people who might not have gone to university further afield. They go to Goldsmiths because it's easy to get to and they can carry on living at home, keep their part-time jobs going, see their schoolfriends, not feeling like a fish out of water in a new town where there's nobody else with their faith/colour of skin, none of their favourite foods available in the shops/canteens, and so on.
The woke kids are mostly the ones coming in from further afield, like one LM.
