I watched this movie on radical Islam and I wanted to see if anyone else has.

What I wanted to know was is why does extremism pop up from ANY religion. On the film radicals had a great hatred of America, Britian, and Israel. In many there was also a hatred towards Egypt. Many of the speeches of imans involve the ruling of the world from the "Black House" or the Kaaba. This seems to me as a threat towards ANY government.

Discuss.
