Eh. The religions are completely different. One is based off of a risen prophet, the other is based off of a dead prophet of the one God. One says turn the cheek, the other says kill that motherfucker, take his wife, rape his kids and blow up his goats.
More or less.
They're about as far apart as you can get, religion-wise. But Somehow I think you were pointing at religion in general.
Anyway, back to castrating moo.
