Prevent? We all know that men's prisons are r*pe dungeons! Everyone fucking jokes about it. Don't drop the soap HAHA SO FUNNEH!!1 Demonic shithole Nazi country run by fucking monsters. The r*pe is the point of US prisons. Death to Amerikkka
The idea that it's "unfair" is based in the idea that women are weak and need protection, that hrt doesn't cause biological changes, that trans women are not real women, that trans women are pervert freaks that can't be allowed around women, it's all the same. There's a lot of baked in assumptions about sex in sports segregation, and they are the same assumptions for bathrooms and locker rooms and prisons. Once the door is open to this shit, it is inevitable that the next Republican regime will codify it.
If the Democrats don't reach some fucking bipartisan compromise and do it themselves.
