Sorry, an overestimate, 1.8 billion. That is still a lot more then if you combine all the people in North America and Europe. My point is, if from 1.8 billion people all were violent f##kers and were trying to kill everyone, world would be way worse off then it is now. As for those that act the way they do, I completely agree, they are scum that needs to be routed out. Calling all Muslims like that is acting like Hitler and saying all Jews should die. And yes, Koran is full of violent verses, but if you read carefully those depict either God's punishment in the past, or warning for the future. None of those incite people to do those things. It is clearly stated that all punishment related to religion, not real world crime, is done by God. It is also described that only God can know what persons sins are and what his fate is, and to kill a person because of religion is to rob him or her the chance to redeem themselves. The same mistake was done by Catholic Church during dark ages. Nowhere in Bible does it say you should kill anyone due to religion, yet crusaders took it upon themselves to act like God and decide who needs punishment. And even back then you had orders within the church, such as Order of St. Francis, who did marvelous good deeds and tried to stop the idiocy.
Extremism is the worst part of human nature, even while we all tilt to it a bit. As such, we should always be careful of not becoming what we are fighting against.
