1 in 50 prisoners say they are transgender
Why do you need proof or citatations, Rose?
Acceptance without exception based on self declaration. That's the Stonewall position and the one you appear to be arguing for?
Why does it then matter how many prisoners - or anyone in society - make such a self declaration? Why do you want "proof"? It's either acceptance without exception on the basis of self declaration or it's not.
Why do you need or want proof of numbers? Why does it matter to you? I'll be frank: it doesn't matter to me either. One male rapist in a women's prison is one too many. Heck, one male in a women's prison is one too many.
I can't work out why you're fixated on seeing proof that it's any particular number. Is there a number that would change your mind if it was too high? If so, what number?
