Nice piece of revisionist history you present there, Sher-e.  You conveniently forgot to mention that Islam has only ever been spread by the sword.  Spain, for example, was invaded by Moors from North Africa in the early 700's.

You also conveniently forgot to mention that the New Testament doesn't call for any mistreatment of non-Christians.  Contrast that with the Koran's teachings regarding nonbelievers.
