Would you expect women in prison to feel comfortable around a trans man that looks like Buck Angel?
Perhaps not. But Buck IS female. So, if there are only male and female places available it is on the women's prison to look for ways to manage that. And I think many women would, in fact, be ok once they knew Buck's status - I know I would. Not all, and that would need to be managed both for the distress to those women and the risk to Buck. But I certainly don't think a male prison would be the right place if nothing else because however much risk you think a trans women is at in a male prison, the risk to a trans man, even a fully transitioned one (which as far as I know Buck is not), will be worse.
Would you expect a trans woman who has been on puberty blockers, lifelong hormones and top and bottom surgery to be anywhere near safe in a mens' unit?
Interestingly, the few fully-transitioned males in prison ARE in the male estate and are not the ones putting in requests to transfer. Many men are at risk in male prisons - are trans women especially high risk, or is it just that, unlike the others, they have another option? Either way my answer here is the same as above - if there are only male and female places available it is on the men's prison to look for ways to manage that.
If you're a reasonable person without a transphobic agenda, the obvious answer to those questions is no.
I am a reasonable person without a transphobic agenda. And I do not agree with you. Certainly, I don't think a reasonable person without a misogynistic agenda should be considering women's prisons, and the women in them, to be a handy resource for the safely and comfort of male people who for any reason cannot be incarcerated with men.
Because sex essentialism doesn't work in every case. Treating demographics as homogenous groups will always come at the cost of individuals on both sides of the coin.
Yes. But ignoring demographics has a greater cost. Life isn't perfect, but doing nothing because we can't be 100% perfect is far worse than doing the best we we can.
Have you read my earlier post about why we segregate? It's not some ideological idea of "sex essentialism", quite the opposite.
I agree humans should not be held up as ideological concepts. We should make pragmatic decisions based on the problems we have to fix and use the best tools, however imperfect they are, to fix them.
Right now, the tools we have are based on binary sex. Better tools could be envisioned, for example more third spaces. But until those tools actually exist, we must do the best for the people who are in need right now with the tools we have. So if you want that to change, worry less about exactly which males should be allowed to use women's resources and focus on getting them support that's properly designed just for them.
