i should have said which % of the muslim pop are terrorists since thats your primary concern?A muslim that is true to the koran (which by any standard, what is required in the treatment of non believers in the writings of the koran, would be considered destructive ) and you consider good and nice can only be:
1) A good actor.
2) A good liar.
3) Not a real muslim.
4) A hypocrite to their religion.
What percentage ? I have no idea. How many actors, liars, not real Christians, and hypocrites are in the Christian faith? I'm gonna go with about the same.
