I agree with you. For me all Muslims are terrorists. They do not consider aggression against non-Muslims aggression. Islam preaches violence as a method of dealing with dissent. I never do.
I am not sure whether a terror group has any religious inclination because they kill people from all walks of life and even Muslims ,so i wont say that all Muslims are extremist .I agree the part that Muslims do think that they are superior to others as they think they are the true followers of god and they tend to force that to others but that does not mean every Muslim can be called a terrorist.
Wikipedia has a pretty good article on Islamic Terrorism.
Wake up and see it is what it is.
