I have always been offended by the term "homophobia". Not only is it terrible Greek/Latin ("homo" meaning human, "homophobia" should mean "fear of humans"), but it also implies that anyone who's got a moral objection (or even just an aesthetic one) to the kinds of things that gay people do at Pride marches and some of the behavior they showed while trying in vain to defeat Prop 8 in California last year is somehow "afraid" of gay people.
It is not fear when I show revulsion and disgust at people shoving their sexuality in my face. It is revulsion and disgust. Let's get our terms straight because nothing says "pot kettle black" quite like people pushing for tolerance by using bigotry toward anyone who doesn't fall into lockstep with the cause they're demonstrating for. I consistently vote against gay marriage and gay rights just because those people piss me off on such a visceral level that I go into "whatever you want, I'm doing the opposite" mode. I find the religious folks and the "defense of marriage" advocates clean-cut, friendly, likeable, and worth tossing a vote to since I personally (as a married heterosexual guy) have no dog in the fight.
As an aside to the above, my closest male friend is gay and "came out" long before I met him. I had him working with me when I ran a professional gambling operation and he was loyal, coachable, friendly, and honest. He still uses me as a job reference because I have nothing but good things to say about him. The key point is that sexuality (his or mine) is an off-limits topic of conversation. I don't want to hear about who he's been spreading his ass cheeks for (dude covers his sex life in his blog, and I read his blog knowing what I'm getting myself into) and I don't tell him about how great it is to fuck women---I've got "beer commercial buddies" to swap those kinds of stories with. If more gay guys were like my best friend (and if fewer lesbians were man-hating feminazis, at least toward me), I'd be wholeheartedly in favor of their cause.
