God wishes for us to love one another. Passing a law to prevent hate towards the gay community i think is more along the lines of God's intentions.
Being gay isn't against God. However, God dosn't exactly insist Gay people have sex. He's also against adultery, for reasons that support our mental and physical health. We have not followed Gods words, and we still don't pay mind to the aftermath as being the consenquence of disobedience. God said there would be disease, that of which does not originate from Gay sex, the disease will spread only through the infected, straight and Gay.
Another note. Just because one is Gay does not mean they take part in sexual acts with members of the same sex. God does not hate someone for being gay. I'm not even sure if God is capable of hating, as there is a difference between Hate, and dislike.
