Your initial question was "Islam," not "extreme Islam." Religious extremism of any denomination is dangerous.

The fundamentalist Muslims are certainly causing the most trouble, but other religions don't have fundamentalists that are trying to take over the world. Fundamentalist Christians don't blow up buses full of children and fly airplanes into buildings in the name of Christ.
The constant turmoil in the middle east is not being caused by Christians, Jews, Buddhists, or Hindus. The middle east is in constant turmoil because it's been infected with a toxic religion, Islam.
