If you genuinely have an issue with trans woman being on a separate wing within a woman’s prison, segregated from woman there, then the issue is with you - not them.
It doesn't take away the risk of them being a predator, though.
No, neither does being born female. Yes, men commit more crimes but we cannot make spaces completely risk free. And if my daughter ever came out with the ‘ladies toilets is a space space’ bollox, I would put her straight. Given my experiences of toilets, I’d say you’re probably far more likely to be beaten up or robbed by a group of girls in there than you are to have a transwoman try and attack you.
