In the Christian world, as you remember, Christianity is in the 21st century, Islam is in the 15th century. I don't mean to say that Islam is backward; I mean to say that there are certain experiences that it hasn't gone through. Christianity had the great religious wars of the 17th century. Islam, fortunately for the Muslims, did not have that. Christianity worked out a system of toleration. Islam was always more tolerant of Christendom.
