This is what you believe, this is what people who benefit from you believing that are telling you but it's nonsense. There may be poor fundamentalists who would gladly kill for religion but they have no ability to act on it. Only the rich and powerful have that capability and they're also better educated.

If you truly believe there are a group of people for whom religion is enough to make them want to kill, then the solution would be education and financial investment. Middle class people make poor martyrs. The idea that the only thing that can be done is murder them is sickening.
