I'm fine with gays, they don't get in my way any more than a girl who really liked me but i didn't like her would. They're a member of the society same as anyone else is. If our if not it is a choice, they still have the right to be gay. Say somebody isn't christian, that doesn't mean we should start knocking down christian churches and all that, it means we should learn to just be fine with them, acceot them, and stop making them get in our way. This almost hits your main argument of the bible, it's just like two equal swordsmen fighting, except one has a bigger sword than the other. As long as each other side doesn't get in the others way, everything will be fine. You both have the free will and should both be able to do what you want to do, but should not be able to impair others from doing what they want.
I also dislike people who say being gay is a disorder. Say someone listens to a band other people don't like, Is that a disorder? Say a kid doesn't like broccoli, is that disorder? It's a preference, not a disorder.
