Most (if not all) western religions are political ideologies.
Islam is the worst.
It is Islam - with its concept such as kafir, jihad, kill the idoltors (those who worship idols) etc etc etc - that tells the muslims to be bad and violent.
Look at history of Mughals, who killed millions of hindus and destroyed thousands of temples, really thought they are doings God's duty.
Unless Islam reforms such barbaric Islamice terrorists act will continue.
