Just so you understand(without dragging this too far off topic) I think of homosexuality in the same sense as a mutation. While it occurs regularly, it is abnormal. Hence the abomination. BUT as with other mutations that occur, it is not your choice. There is no cure. There is no point in trying to "convert" you. In essence it is in my eyes no different than Cerebal Palsy. You're just wired different.
And the acts, quite frankly, are what I find disgusting. But then as a smoker(though trying to quit) I can't hate someone for doing what I find disgusting. I eat Sushi. Many people find that disgusting. There are a thousand things I may do that others find disgusting.
So... to sum up:
Icky is not a good reason to discriminate.
Abnormal is not a reason to discriminate.
Just because I don't like something is no good reason to treat that person any differently.
