How long will it take for people to see things the way God does?

As long a Christians can point to Leviticus and yell "AHA, God hates gays" things aren't going to change. They don't see the irony of wearing their cotton -polyester blend shirts at the prayer luncheon at the Red Lobster and condemning gays for being abominations, then going home to their second or third spouse, and bragging that they did God's will about Prop. 8
