Sure, there are self-hating people of all sorts of marginalized groups, but queer people are the only ones who get regularly talked about as if the people who oppress them are also queer.

You don’t hear about Muslims being oppressed by secret Muslims.

I cannot provide evidence for this, obviously, but it would seem to me that most bigots are bigots because they’re bigoted, not because they’re secretly the thing they’re bigoted against.
