The biggest case for taking hrt while in prison is mostly due to gender identity disorder. It's not so much the lack of hrt, but the things that go hand in hand with gid without treatment, the biggest of which being suicide.
Ideally, they should give out some form of HRT if only for the safety of the prisoner's lives, but then, like said before, when you're a prisoner you rebuke your status as a citizen and identities like this shouldn't really matter, but it's not like people with actual GID are like,"man, if I don't cross dress tonight I'm just not gonna be able to get turned on" or something.
So it's a hard situation. I think that personally, in regards to gender roles, if you've used HRT and you're now incapable of even siring a child, have grown boobs and a female bone structure from the hrt you are now female, penis or not. Likewise, if you're a female who took hrt and you're now growing a beard you're now a man, clit dick or not and think the prisoner's values identities should be accommodated but nothing further than that unless they get dangerous (ie suicide).
That said, the gigantic trans community at gaf confuses me. I'm never sure if many of those people are legitimately with GID, or if they're just anime faggets with a moe fetish.
When I was a kid, I phoned the hospital to ask if they could turn me into a girl even without knowing cheeseburgers existed. I dunno bout them, but a lot of them are suspect.
You know what I hate? This whole "what is gender?" movement. It is what I call progressive open minded hippies trying to be way too progressive and open minded to the point where it is distinguished mentally-challenged. The words "manly", "girly", "masculine", "boyish", "feminine" and such are no bad words to conform to what the man wants. Don't we have words like "tomboy", "nancyboy", "butch" and shit to signify males/females who act like the opposite?
One of the stupidest and idiotic movements I've ever heard.
It's not really new, though. There have been androgynous societies in the past.
