Jesus says to turn the other cheek and love them. He also says to dislike the sin, but to love the sinner. Indeed, I can't find any passage in the New Testament where Jesus is vengeful or angry, except when dealing with the moneychangers in the temple. Disappointed, yes, as in his disappointment with "Doubting" Thomas (who may actually have been his twin brother, Didymus Thomas) and with Peter, at times, but no actual rage.

However, the Koran does say to kill the sinner. Period.

Something I keep seeing here is that people try to say, "Well, Christianity is evil, too." No, not really. There is what the holy book says, and how it is interpreted. No one can deny the Christianity has been applied and misinterpreted poorly, at times. No one. However, that's what it was, a misinterpretation. Again, I can find no place in the New Testament where Jesus commands his followers to kill. Far from it. He teachers tolerance and accommodation ("Render unto Caesar...").

In contrast, the Koran does no such thing. It is chock full of violence, threats, and examples of killing, enslaving, etc. It isn't a matter of interpretation - its there in black and white.

This website does a pretty good job of breaking down and explaining the verses containing violence in the Koran, especially those against infidels: http://www.thereligionofpeace.com/Quran/023-violence.htm . It also attempts to read these verses in context, pointing out where things aren't quite so open to interpretation, but instead are commands to kill.

Check it out with an open mind.
