I fully agree that anyone "trans" should have their own spaces, no problems with that at all. Not bothering anyone else doing that.
But, when it comes to advice/treatment, with things involving conditions that can only apply to biological women, it should be made clear that only biological women are affected, to avoid confusion - especially for people whose first language isn't English.
And, money should not be filtered off from historical "biological female" conditions to apply it elsewhere.
I find it astonishing that so many are having to give headspace, funding and time, to catering for scenarios that cannot exist, and to pander to a tiny (if loud), minority.?
