Yes I have an autistic young adult son who would fit most of what you describe in your OP. He also works in a field where many of his colleagues are similar, lots of them identify as trans / non binary / bi sexual / gender fluid etc .
My son is straight and gender critical, most of his peers assumed he was gay until they asked him recently so he came out as straight 😂. It will be a lot harder to come out as GC. He has tried to remain neutral on this so far but it’s hard as so many of the ( biological ) girls are self harming in one way or another (drugs, binders ) . Of course, none of the boys are ( ‘‘twas ever thus).
Most of them are very nice young people but he’s becoming a little tired of the tendency of a small minority to try and take over the group with their oppression Olympics. These are usually the most privileged white, male, middle class kids (often from public schools ) who are trying to tell others e.g. those who have been asylum seekers/ refugees, care experienced etc that somehow they are the most oppressed.
“ It’s all right for you Maria, not knowing if you father and brothers are dead or alive as they fight on the front line in Ukraine, but my great gran misgendered me. So check your cis het privilege, bitch “.
He has also noticed the tendency of some of them to imply that their families hate them and that they’re completely estranged from them when this turns out not to be the case. For example, he recently visited the home of one of his friends who claims that his parents hate him for being gay and will have nothing to do with him . When in fact they are supporting their son financially through for university and giving him extra money so that he can rent a flat in a nicer area because he’s supposedly scared of being attacked in a rougher area.
My son is aware that it seems fashionable to claim that your parents hate you, when they simply don’t understand you. Which of course is the plight of every generation of teenagers in the west for the last 100 years 😬
So yes there’s a lot of Groupthink and pressure to fit it. Probably like most groups TBH.
