This is a battle for whether America will retain it's moral heritage and all that goes with it or sink into a cesspit of immorality where you can get away with almost any depraved act you could imagine. That is what I'm against.
Mmkay. First off.
The slippery-slope argument is bull. Pedophilia and worse things will never, EVER,
EVER[/u][/i] become legitimized by our society. There's a little thing called "age of consent", and I don't see that ever being struck down, by even the most rabid judge. Besides which, what politician or judge would ever want to be known for doing so? (Bestiality is even worse -- but animals cannot legally give consent, so there.)
Two. Consenting. Adult. Humans. Period.

Secondly, I'll ask again: What in particular about homosexuality do you (and others) find so immoral?
Thirdly, the vast majority of gays insist that their sexuality is not, and was never, a choice. I wouldn't know personally, cause I'm straight, but by that same token neither would you.
And conveniently, the Bible doesn't say whether it's a choice, either.
