And that is the theme that keeps recurring when Islam rears its ugly head in history. They will convert us all or kill us, and that is their sole purpose. I for one, am going to go down fighting the ugliness of their godless beliefs.
(If I only had a sidearm instead of a slingshot...)
Small correction, they do believe in God. In fact, the God Jehovah/Allah. They just believe that Mad Mo came down and gave them a bunch of updates that they plopped down into the Koran and ran with. Even Muslims aren't that bad and mostly keep to themselves. It's those following Islam, and the imposition of Sharia law, that they go the way of the Westboro nutcases...
Spend too much time in the desert heat, and you'll believe almost anything apparently.
