I don´t really know about US prisons, but from what I do know of the NL prisons, the ´dangerous place where guys become someone´s b*itch' is a myth fróm the US. It doesn't really happen in the NL. Sure; there are fights, and there is the occasional abuse, but it's not exactly commonplace.
This raises the question: Are US prisons really that dangerous? Or is it some kind of publicity stunt that looks good in the media, and is a system that tries to fear people out of criminal behaviour, much like the death penalty?
Also; as for the rape convicts: To be honest, the larger percentage of juvenile girls imprisoned in the NL, I thought it was 70% or something a few years back, was convicted for (causing) sexual assault on others.
Me; I think, at least in the NL, a separated prison for trans people is a bad idea. It's a step back to differentiate; it doesn't 'make gender optional;' rather, it enforces the belief of gender reparation.
Not only that, but you'll effectively have a prison with men and women tossed in together. Now, me; I don't really see a problem with that, as mostly, people just stick to their (walled) cells, anyway, apart from meal-time, work hours and social hours.
I do salute the other things, though! Yay for sponsored surgery!
