Here is the conclusion of this thread:

1) Not all Muslims are violent. But generally they are.

2) They see the world as "Muslims Vs the Rest of the World" and are incorrectly paranoid about "rest of the world" hatching conspiracies against them.

3) Religion (or the cultural misinterpretation of the Koran) is the main cause of them being violent. A Muslim child brought up outside of Muslim culture will most likely be less violent if not at all.
