Christians aren't trying to make homosexual behavior illegal, they are trying to keep it illegal. It's the queers who are trying to change the law. As I pointed out in the post to which you replied, Christians do quote the Bible to other believers, but you don't have to look far to see the scientific and medical reasons for keeping homosexuality illegal posted by Christians on this board.
Just because Biblical values happen to line up with reality doesn't mean that attempting to legislate reality is an effort to create a theocracy.
Shalom.
