And just in case you suspect that such situations don't arise with gender I can assure you that they do.

Michigan women's camp refuses to accept even post-op trans women. A lot of the more essentialist wimmin's organisation have similar reservations.

I actually once hd a bizarre conversation with the organisation of a dance festival as to exactly where the bounds of acceptability for trans men might lie. Transvestite..no
Accepted for transgender treatment but pre-hormonal..no
Pre-op but passing...yes
pre-op but likely to cause comments...no

We were deep in Heydrich territory at that point and I had to quieten my utter outrage because these bigoted fools actually thought they were trying to be fair.

All of which were slightly undermined by my question at the end of asking them how could they know if a woman was really a convincing transvestite. Unless they're willing to have intimate examinations of all delegates they were really hoist by their silly prejudice
