I've already told you I'm not fixated on Florida.
Then where do you want to talk about?
So you do know the mechanism? Please explain it.
In the US, the basis for overcoming anti-discrimination law of this kind would be the rational basis test. Which means that such discrimination has to be rationally related to a legitimate government interest, real or hypothetical.
It would go something like this, I think:
Trans Prisoner Who Has Committed Brutal Acts of Violence Against Women: "Women's prison, please!"
Hypothetical State Where They Give Two ***** About Prisoners and Trans People are Legally Protected from Discrimination in Prisons: "Upon review of your request...no."
TPWHCBAoVAW: "Racist!"
HSWTGTSAPaTPaLPfDiP: "Lol."
TPWHCBAoVAW: "You're discriminating against me!"
HSWTGTSAPaTPaLPfDiP: "Yeah. We get to do that because you pose a risk to female prisoners."
TPWHCBAoVAW: "I'm going to sue!"
HSWTGTSAPaTPaLPfDiP: "Ok. Have fun proving that we
don't have a basis for doing this, because that's what you need to do."
And why do people oppose such reach? I think you can figure it out for yourself.
Because they don't want hyper-permissive self-id laws, obviously.
Still not seeing where the danger is.
