I think there is a difference between intact males and surgically 'transitioned' ones. Yes, both are male, but the one who has undergone surgery is (a) obviously committed to the cause, and (b) much less likely to be a risk to women.
It is when a man pretends to be a woman in order to access female spaces that I object. Whether or not he intends to harm women is irrelevant. My husband and son wouldn't harm women but both are able to understand that we don't want them (or their friends) watching us undress or being in our spaces when we are doing personal things.
Most trans women are heterosexual men, and most do not take female hormones. Look at how many claim to be lesbian, and object when real lesbians don't want to have sex with them. They are men who are attracted to women, so should not be in female spaces.
There are very few sex-based spaces. Loos, changing rooms and some medical spaces are the only ones to spring to mind, although there are things like women-only times in swimming pools and so on. The reasons those places are single-sex is because they are places where women remove clothing or are otherwise vulnerable to attack by men. Not all men, to coin the phrase, but the risk is always there. Men are men, whatever they wear and whomever they claim to be. The risk, therefore, remains the same regardless of how they 'identify'.
As I have said several times, where new facilities are being built there is no reason why they can't be enclosed spaces, so long as they are sensibly sited (ie not along corridors away from main seating areas), but existing buildings are not always compatible, and there is not always a budget for providing brand new plumbing and accommodation.
What did you you think you would have by your current age that you don't?
