extremist everything

It seems these days you always hear of extremist muslim terrorist, but no one ever talks about the extremist christian vigilantes of Washington who drive the "Co-olition of the Co-erced", like as if we would ever hear CNN talk about extremist christian terrorist who carpet bomb a northern Iraqi City to root out Sunni Muslims. We are in the middle of a new holy crusade, it is the extremist christians against the extremist muslims, the USA versus the Arabs.

We never hear of George W Bush as a extremist christian terrorist leader, or the extremist christian crack down on anyone but the whites called the war on terror. Just what are white people afraid of that they call what they don't know "extremist"?
