We just happen to be the biggest Satan. It is Western values that threaten them. We're just a symbol of that. Had Napoleon conquered the world and we all spoke French today, they would have crashed the planes into the Eiffel tower and the Arc d' Triomphe.
It is their observation, and they are correct, that a country which practices Islamic Fundamentalism on a country-wide basis is destined to forever be an economic backwater in a world where other sets of values lead to things like men on the Moon or vaccines against polio. And yet everything they know tells them that Islamic Fundamentalism is the right way to live. It is the right way for all people to live. There is no other right way.
Therefore the West must die.
