True, and Christianity has its share (maybe more than its share) of horrible bastardizers. However, the only current phenomenon without equal is Islam.
And it bears repeating that I agree with Leah-Ann that it is a minority of believers and should not be an indictment of the entire faith. The problem is when people try to draw a moral equivalence between the violent tendencies of Christianity and Islam. They just don't compare -- period.
And, to do so only perpetuates myths that make the world more dangerous by drawing a moral equivalency where there is none. Very bad!
