Perhaps no trans women with a history of rape should be allowed into women’s prisons
So male people can be housed in prisons alongside women safely as long as they haven't raped any women beforehand? I think, respectfully, you need to work your suggestions to their logical end here. Risk analysis is based on groups. TW are male people, and male people as a group are categorically, provably, a huge risk to women as a group.
It's not the transness we wish to keep away from women, it is the males. This is why we ask TWAW believers to define terms. Because the 'Trans' bit is irrelevant in the contexts we care about. The male sex is the issue, and no male is a female/woman, whatever he feels inside, however nice and harmless.
So when you suggest that TWAW, therefore they should access everything a woman can, you are basically saying 'A man may take space from a woman if he sincerely believes he should be able to'. And I promise you many male people will agree with you, but it's not feminism by any stretch of the imagination.
