Your point was that "dangerous Islam" arises in politically troublesome areas. This does not explain why 7% of American Muslims responded that suicide bombings are sometimes justified against civilian targets in defense of Islam 1% said often, 5% said rarely, for a net of 13%.
In other countries:
Great Britain: 24%
France: 35%
Germany: 13%
Spain: 25%
43% of U.S. Muslims think the Koran is the literal word of God.
20% of U.S. Muslims think the Koran is the literal word of God with a single interpretation.

This does not seem like the dangerous ideas of Islam are contained to areas of political unrest.
