They hide behind the US Constitution. Freedom of speech and all that.
It was in one of the articles I read that the 2 Baptist groups don't recognize them as a legit Baptist church. In the same articles it was suggested that the government should pull their tax exempt status. I think it's being considered.
If they did and since the two Baptist leader groups don't recognize them as a legit church, they would be just a pack of trouble makers and subject to the full weight of the law.
It's stupid how much they can get away with.
