The reason Islamic fundamentalists so rarely quote the actual Qur'an is because it doesn't agree with them. And the western media help them.
Terrorists teach that Islam is violent. Western liberals accept Islam as violent and demand that everyone respect the "other culture". Islamophobes believe both the terrorists and the liberals and then paint Islam as a violent religion that must be opposed.
This ultimately hurts Muslims most, because they are the only ones who cannot win.
