Looks like I missed all the fun, although I have to say, I laughed quite a few times while reading over the last 10 pages of this thread. (Sorry Steve, I didn't get to vote for you.) It's true though. Homophobes are typically people who are so insecure about their own orientation that they fear that any gay influence will cause their repressed homosexual tendencies to erupt; just as those who hate atheists or skeptics are typically so insecure in their beliefs that they fear any irreligious influence will cause their faith to come crashing down like a house of cards.
I did want to address the original question posed by this topic though, and from a biblical standpoint. There are several reasons why the bible condemns homosexuality, none of which most Christian homophobes seem to be aware of, aside from the fact that it's an "abomination" or whatever they like to call it.
1. It's dirty and therefore more likely to transmit STDs. To put it another way, it was meant to let things out, not in. If you look at the rest of Leviticus, you would see just how primitive and superstitious an understanding of infectious disease the ancient Hebrews had. If a man came down with disease after having sex with another man, then they assumed that obviously God had to have been punishing them for their act. This was a time before protection or safe sex, and a time when medicine as we know it was practically nonexistent.
2. It does not result in procreation and therefore violates one of the most sacred covenants. If God told you to be fruitful and multiply, it was an order, not a request. In the world of the ancient Hebrews, life was brutal and the survival of the tribe depended on being able to make plenty of little Hebrews, specifically males to work the fields or fight in wars. Women were valued primarily for their ability to make babies. Also, considering the highly patriarchal nature of Hebrew society, the most degrading thing one could do to a man was to force him to assume the sexual role of a woman.
3. The book of Leviticus, like the rest of the Pentateuch, was most likely written during the time of Babylonian captivity. The Jews, being a people without a nation to call their own, had only their tribal customs to give them any sense of identity. Given that certain civilizations of the time, including the Babylonians, had fewer laws of this nature regarding 'sexual morality', the Jews believed that they could better preserve their identity by differentiating themselves from their captives. This, incidentally, is also the origin of many of the other bizarre laws found in the Torah, such as the dietary restrictions.
The question for Christians now is, do any of these factors still apply today? Of course not. Besides, one could make a fairly cogent argument that the god of the bible is gay (which I won't get into now). This would further explain why homosexuality was punishable by death. It was a capital crime under Jewish laws to impersonate a deity.
