There are transwomen who would clearly be in significant danger in a male prison, have never harmed a fly and present absolutely no danger to female inmates. Suspect these are a tiny minority, but still deserve to be treated with respect.
The vast majority of natal men aren't rapists. Yet don't allow any men in female single sex spaces (for the sake or argument as some people want to change this)Not because all men are rapists. But because some are, and we can't tell which so we don't allow any in, in order to mitigate the risk to women.
There are especially vulnerable men due to physical disabilities, learning difficulties etc who have 'never harmed a fly' (e.g. a non violent crime) who are at much greater risk than other males in a male prison.
But they are housed in that prison because they are male.
And they are not moved to a female prison, even though they would arguably be safer there, because as males they still present a potential sex specific risk to female prisoners.
Why should a trans woman (who could be physically very fit, strong and as able to defend themselves as another man) be offered the protection of being housed with women, when far more vulnerable men aren't?
That's a genuine question.
The answer is that we don't segregate prisons based on case by base vulnerability, we segregate them based on sex specific vulnerability that presents sex specific risks and sex specific outcomes.
