The Origins of Fundamentalism

What people call fundamentalism often covers two very much opposed phenomena. What we usually refer to as fundamentalism you know pet Roberts and Jerry Falwell they kind of that that kind of people i would even deny to them the term fundamentalism. How do you relate either envy or not let me be very naive  i don't have any illusions about Tibetan Buddhism but the bet Tibetan Buddhists that i've met or armies again are authentic fundamentalist.
