Why do muslims believe its ok to murder people for drawing mohammed?

B/c they're Muslims. They're insane. They are the worst case scenario for what can go wrong with a religion. They are the poster child for why atheists don't trust theism. Red Ribbon, no one knew who to kill. As for your one verse advocating peace, how convenient. It's like going to a Bob Evans and finding out that they serve vegetables and concluding that it's a vegan restaurant.
