No one is trying to prevent trans people from using the toilet.
There are toilets for people of both sexes. You have yourself confirmed that there is no safety issue, that there is no evidence to suggest that trans women will be attacked in men's toilets, and so literally the only reason for them to use women's toilets instead is because they want to.
You're saying that what they want matters and what women want doesn't.
That women don't need single sex spaces but trans women can't possibly be expected to share spaces with members of their own sex.
That if we oppose trans women using women's spaces we are denying their right to exist in society, but if female women feel unable to use such spaces knowing that they may encounter someone with a penis they can stay home.
The level of misogyny you are displaying is utterly breathtaking.
I strongly suspect you are trying to provoke me into saying something against the Talk Guidelines so you can frantically hit the report button and have me banned, so I think I am going to quit while I am ahead and not give you the satisfaction.
Good night.
