Implemented under the radar
They’re already doing it.
Over here we have women bleeding to death because the hospital refuses to end their pregnancies, and over on this other side we have women being strip searched by male cops and female cops forced to strip search men because the police refuse to protect women.
Which brings to mind the old definition of a cop: a petty crook who has found a soft racket. Also Lord Acton’s dictum: power corrupts, and absolute power corrupts absolutely.
So if one is being arrested, would it be advisable to claim to be of no gender at all? Or one of the more obscure, imaginative genders? Or gender fluid, and keep yelling out a different gender every time an officer attempts a strip search? Or will it turn out that the gender identity of the suspect is actually of no consequence at all?
