Because we have yet to see a good Muslim or Hindu president, whose country is almost devoid of religious violence, and all victims of violence, regardless of creed, are given immediate help. As for Buddhists, well...*glances nervously at Burma*
BTW, Hitler may have been raised Catholic, but he was an anti-theist, not a Christian. And Bush may not have been perfect, but who would YOU have wanted to see at the helm after 9/11? May I remind you it was the Muslims in control of Afghanistan who attacked us, not the other way around?
