The idea that Islamic rule is about peace, freedom, and democracy is about as defensible as the claim that Nazism is about peace, freedom, and democracy.
I think we should be very careful when it comes to appeasing Muslims, White Nationalists, Stalinists, and other groups that for some strange reason find Ron Paul's message of freedom appealing. We should be happy for their support, but always distance ourselves from ideologies that are ultimately collectivist and hostile toward liberty.
