I agree that the concept of "everyone else is wrong" does provide the foundation for actions of hate; however, I don't see the direct correlation. In my experience, you can basically slate up all religious people into two groups (remember, this is a generalization). First, we're right, and everyone else is wrong. Second, it doesn't matter what you believe, as long as you believe something. Each group's idea opposes the idea of the other group, but most tend to practice tolerance, as was mentioned before. ie, even though you are from a school of thought different from my own, it's cool - I respect you and your belief. Now, translating the idea of "we're right, everyone else is wrong" into the idea of "not only are they wrong, but they are inherently evil and must be destroyed" is the radical problem we are dealing with. I don't find anything wrong with the afformentioned muslim school text.
