"Don't hurt me."
He didn't back down, and he's not worried about himself, believe me. He's worried about the Christians in Muslim lands (such as the 70 yr old nun who was gunned down by a Muslim in a Somali children's hospital today), which is probably the only reason he's even giving these idiots the courtesy of a reply.
But he knows that this situation has got to be dealt with, and it's going to cost Christian lives no matter what he does. Think about it, how would you feel?
