In a video I watched recently on non-binary sexuality in comics, Charles "Zan" Christensen proposed an idea I hadn't heard before - that the root of homophobia was, in fact, biphobia.
Studies have shown that intolerant attitudes towards gays and gay rights statistically correspond to measurable arousal towards homosexual pornography - resulting in the common stereotype that the most vitriolic gaybashers are, themselves, closeted homosexuals.
Zan proposes that, rather, those people who insist that homosexuality is a choice must be those people for whom that statement is a reality - that the gaybashers in question are, in fact, on some level, bisexual, and assume that everyone else is too.
Obviously, there are varying levels and types of homophobia, and one should be wary of any statement about human psychology that contains words like "all", "always" and "never", but I'd say Zan's reasoning is pretty air-tight.
(Wednesday evening, INT: WW and SW's place)
JH: Actually, to be perfectly honest, I don't think the government should issue you two a marriage license.
SW: Really? Why the hell not?
JH: Well, marriage isn't just about two people. It's about community, it's about tradition... and yes, it's about religion, it's about God. A wedding is, fundamentally, historically, a religious ritual, a covenant between a man and a woman and their society and their deity to establish something beautiful, sacred, and permanent.
JH: So no, regardless of how much you two may love each other, and regardless of how "fair" it might be, I really don't think the government should have its metaphorical collective arm twisted into doling out a homosexual marriage license to you guys.
WW: Wow. I gotta admit, I didn't see that coming. I'm actually kinda hurt, here.
JH: Of course, I don't think the government should be passing out heterosexual marriage licenses, either...
