Females are supportive of transsexual women in their spaces - people who have fully transitioned including surgical transition. Females are, in general, not supportive of people with penises being in their spaces.
I used to hold no objection to surgically-transitioned transwomen in the less intimate spaces such as public loos. I've changed my mind, for two reasons. One is that I have realised that there are some surgically-transitioned transwomen who have transitioned for fetishistic reasons, but this is not the main objection.
It's the camel's nose again. It's impossible to screen transwomen and say, you're good to go but you can't come in. The latter group throw a strop and scream about transphobia. We've all seen Boudicca insisting that surgical transition shouldn't be a prerequisite because reasons, and that's par for the course. Also, guys, we can't tell who has had genital surgery and who hasn't, just by looking at them. You're back at the genital inspection requirement. If even a small group of people who are physically, phenotypically male is allowed in, this removes women's ability to challenge anyone who is phenotypically male. This is a problem. In practice, it means that any man at all can enter unchallenged.
