Just because a muslim group was behind 9/11 it doesnt mean that all muslims are terrorists. That is completely naive to say so. Some of the loveliest people I know are muslim, they wouldn't do anything to hurt a fly.
And by the way, you get terrorist groups from all religions, not just muslims. It all depends on the nature of the person, not what religion they follow.
I'm sorry, but I think you need to keep your prejudiced and narrow minded thoughts to yourself. Asshole.
