It's about gender. Gender structures our identities more than almost any other concept, and homosexuals upset the wonderfully simple conceptions of gender that many people have (gays cannot be manly, a gay man is letting himself be treated like a woman, a lesbian is giving up her duty of finding a male phallus, homosexuality being associated with submissiveness, weakness, or other things that are "anti-masculine", ect, ect, ect.), which leads them to put up defense mechanisms (homophobia) in order to identify these people as threats to their subconscious model of reality.
For many people, openly accepting a homosexual means having to rethink what it means to be a man or woman, which cannot be done without rethinking yourself. You know that it isn't a good feeling to be confused or to face identity changes, most people subconsciously resist this like the plague. So, to avoid the unpleasantness of having to re-evaluate oneself, they simply see homosexuals as a "thing to be avoided", it's their brain trying to maintain internal consistency via subconscious defense mechanisms







Furthermore, let me clear up another favorite lie of the GLBT crowd: Not agreeing with or supporting homosexuality does not automatically make one Anti-homosexual. I don't care what you do in your bedroom. I only want to know why you have to let everybody know your proclivities. Shut your homosexual pie holes and there wouldn't be any problems. I don't run around telling everybody what my favorite orifice is.
