Well, historically, Muslims have been very tolerant to other faiths.
When the Moors ruled most of Spain, Christians were free to follow their faith, but not so the other way around when Christians were in charge.
Also, it was the Western Crusaders who travelled all the way to the Middle-East to pick a fight with the Muslims.

At the moment, Islam has the mutters running riot but in a few years who is not to say that it won't be Christian mutters who are causing havoc!

Religion is the real enemy!

Any group that is guided by ancient texts that can be interpreted in a myrad of different ways is very dangerous!
