Have you ever read the Koran?
In it you will see a clarion call for Muslims to destroy the infidels. It's not a vague reference, either. It's clearly stated.
Have you read the bible? It does the same thing (Exodus 23:20)
However, I'm willing to realize that not all Christians are willing to accept the 'commandment' to destroy anyone who supports a God other than the biblical one. Why is it that you believe all Muslims automatically accept every single tenet of your interpretation of the Koran?
