It was on fire when I laid down on it.
If your leader's authority over you is supported a great deal by your belief in a sanctioned religion, the rise of other religions are a threat to his power structure.
If an authority says, "Do not do this, because God says so," his law is powerless over the one who does not believe in his god.
Or the leader and followers may actually be BELIEVERS in a particular faith.
And - get this - they may actually be right!
There is truth out there. And believers in that truth.
