Hello, I'm part of the yoof, and I'm so millennial that I have multiple avocadoes in the fridge this very minute. I'm also very working class, and have a history of being very pro-trans rights because of having lovely trans friends from the LGBT society.
But not quite as pro trans as you say I should have been.
I am still pretty happy to share women's toilets myself with transwomen, because as you say, I worry about them being subjected to male violence in the men's. However, I always saw that as a courtesy to be extended to transwomen, not their right to be demanded, and I did think it had to be balanced against other women's interests. I am, for example, aware that Orthodox Jewish women and observant Muslim women need single sex space, and I have always taken it for granted that this need should be respected. Do you? I always thought that the best way to accommodate my trans friends was the addition of extra single-occupant unisex toilets in all new buildings. (In retrospect, I'm not sure they realised I thought that.)
I don't know what my late mother thought of transsexuals, because it never came up, but I know that she wouldn't have been able to use the ladies if Alex Drummond was in there. I'm not really bothered about sharing public toilets with obvious bloke, due to years of 21st century social conditioning
but she would have been. I know that she needed a female HCP for any intimate care or screening and preferred it for other issues too. I know that if she had been faced with a person like Julie Marshall on a hospital ward, she would have self-discharged unless she was unable to physically leave the hospital. She would have been effectively excluded from medical care which would have reduced her life expectancy to even younger than it was.
There is no point, then or now, at which I would be or have been happy to agree that my lovely mtf trans friends' wishes to be included in the women's ward were more important than my mother's right to feel safe in hospital or the rights of anyone else's mother. Trans people need to go in private rooms, and in fact that serves their needs better than public wards.
I am a terminal rule-follower myself, but I am sort of prison-adjacent in that I know men and women who went to prison in their own youth. Based on what they have told me of prisons, I feel very strongly that women's prisons should be single-sex.
