Why should a woman, who has a much higher likelihood of having experienced trauma at the hands of males, have their already likely poor mental health risked by living in confines with a male.
You may use the word 'transwoman', but they are MALE.
And considering women also seem more likely to be able to accurately sex a person even after 'transition', why would you think this was at all appropriate. What is it that you think disguises their male cues? Even if they don't have a penis anymore?
Just how many of them do you think have the extreme cosmetic surgery where their face is peeled all the way back and they have bones shaved, implants added and their hairline lowered, the space between lips and nose narrowed?
And then just how many do you think have their voice modified via more surgery?
I'd suggest a woman in a woman's prison on a murder charge is more likely to intimidate or hurt another woman than a transwoman serving time for tax evasion.
Then you are simply ignoring that female inmates being in a prison with males they cannot just walk away from are being harmed simply by those males being there.
And that is also not acknowledging that a male may still have a functioning penis and that there are already women who have told their stories in the UK where they have been traumatised by the sexual harassment of wanking males or males who love to exhibit their erection in the showers.
Just because they are not in for a 'violent' crime, doesn't mean that they are not abusive, or that they have a violent history but just have never been convicted.
You also ignore that transitioned males who may have grip strength in the lower 25% of all males, still have grip strength stronger than women in the 90th percentile of all women. And that is just grip strength.
Your comparison of 'danger' of women vs women seems to be unable to acknowledge the power of a weak male vs women.
That is fine. That is your choice.
But you need to own that you either cannot acknowledge that those female inmates have needs that should be considered, or you choose not to.
