Fundamentalists and Terrorists

What it means to be a Terrorist Fanatic
We need to be able to make sound decisions and look at people with fairness. We need to look at some very important aspects concerning fairness. In the study of religion we use the label "fundamentalist" and attach it to a large variety of religions to segment a certain type of activities people are taking that delineate them as "being" a Fundamentalist. What is most important is that we maintain our ability to very quickly judge actions as being right or wrong and very slowly if at all judge people.
I believe you will find that there is a gray area of those who consider themselves to be "Fundamentalists" in all of these groups. These are those who hold their religion is the "only" source of truth, their scripture the "only" inspired "word of God, Allah, G-d" and they are "willing" to defend their position with physical force if needed in their mind. Being "willing" to defend a position that cannot be proven with fact as true is not terrorism. Taking action to preemptively attack a supposed "enemy" as part of their "willingness to defend their position" is terroristic in nature.
Though groups that are founded on hate and hating others exist and sponsor terrorism and promote the belief in terror as a viable process of social change; that alone does not make all of their adherents as culpable as those who own, operate and perform the tactical aspects of their organization.
