Ok he is anti-superstition and he wants to ban black magic.

There are two ways to view “superstition,” either as contrasted to a monotheistic faith, or as contrasted to an atheistic world view.

Some atheists call belief in God a superstition. God returns the compliment to their beliefs, of course....
