That makes no sense. Other factors aside (I know WB are a bunch of lunatics) Oklahoma is one of the more deeply Christian states in the US. If God wanted to send a message wouldn't he destroy some of the least Christian states?
That said, sure they were chased out but they got exactly what they wanted...media attention. The faster people realize that ignoring them and not showing anything on the news relating to them, the faster they will be gone.
To be honest, if God hated gays, why wouldn't he just destroy them?
What's a legitimate reason to be antigay?
I think the big issue here is not neccisary being antigay, its being antigay and then compaigning like they are some sort of ferral creature that needs to be put down. It doesn't matter to me what you are, but if some people are against it because of their religious beliefs etc then so be it, but do it in a respective way.
