Are we seriously going to suggest that queer people are to blame for our own oppression?
No...?
I've never seen anyone make this claim.
It makes some sense that the people who violently bottle up all of their impulses, who are then the most unhappy about it, just to fit in with their right wing community are then the ones who A) think about it the most often, and B) imagine that the "devil's temptation" and the repression thereof is normal for most people, when it really isn't.
—But this isn't the same as saying that only gay people are homophobic. It's just a kind of pathology that leads to being the most militant about it. You end up working the hardest to fit in because you're the most at risk of losing that.
But even more than that, I'm not sure I believe straightness is really "real." If everyone is "a little bit queer", and conservatives are the only ones rejecting that, then this is just an indication that their ideas don't really pan out. They would claim straightness is normal, default, but they can't hold themselves to it; it's not actually possible.
So, those are two different answers to the one problem you've put forward, but in either case, or neither, I don't really see this as the gays attacking themselves. The right wing is just kinda wack, you know?
