thats not remotely surprising though is it?
he was on this issue way before most people even knew it was a thing & it's clear from what he's said that he honestly thought that once it was pointed out what the obvious problems & consequences of men self ID as women was pointed out, ppl would go "oh god yes we hadn't thought it through properly, obvs we'll put safeguards in". Instead in a truly kafkaesque manner, ppl he regarded as friends and colleagues doubled & them trebled down. He was ostracised completely from his professional & social circles, he couldn't work, his marriage fell apart, he had cancer, the musical he was relying on to keep him solvent was cancelled
all because he refused to say men can be women and refused to be polite about, because he pointed out the absolute insanity of saying a middle aged man in a dress is somehow not only no longer a risk to women but is now more vulnerable than actual women. All while everyone at the time was saying "no no you're a hideous bigot for believing this"
most ppl would have caved, many did but he never did
I'm frankly amazed he has any sanity left
