Uh, you're using the word "Christians" to refer to white people. How do you know the religious orientation of the Vegas shooter and what not?
Further, where in the Christian doctrine does Jesus state 'kill and rape them!' I mean, Jesus flipped a table one time. Tried to whip some bankers for taking advantage of currency issues, and he said something about trading a coat for a sword, but he never approved of raping and killing. The savage, Muhammad the Borrower however did. Why? Because western civilization failed to civilize his barbaric tribe. We failed to bring our glorious culture to those caveman, and Muhammad made up a story, and now we're dealing with the consequences.
