The idea that only secretly queer people are homophobic is in itself homophobic and I'd like to see it stop being perpetuated in queer communities. Heterosexual people are responsible for heteronormativity, and therefore the vast majority of homophobia.
Are there some closeted, self-hating gays out there? Yes.
Does that mean every homophobe is a closeted, self-hating gay? No.
But that’s not what this is saying. It’s saying that homophobic (or outwardly homophobic) politicians are closeted self-hating gays. And although I agree it’s a stereotype and obviously not true for all homophobes, I don’t see how pointing out the hypocrisy of this category of politicians it’s homophobic. Many people including myself don’t care if you’re a guy who enjoys tasting some primo quality cock, but if you’re doing so while promoting or pushing anti-gay laws then yeah I’m going to laugh at you for being a hypocritical shitbag.
