Ecoterrorism isn't an ideology.
Exactly. The far right wing nutcases don't have the mental capabilities to understand that.
Ideology is a rigid set of beliefs—a system of beliefs—that compels people to behave in particular ways. Ideology, especially the extremist version, does not allow for compromise; it is a Manichean system of reasoning that does not serve as a basis for day-to-day political activity. It is in fact the antithesis of politics, a system that thrives on debate and compromise. It is also distinguishable from philosophy and religion, which guide how individuals choose to live. Ideology is about how a few individuals think society should be governed. Ideologically driven behavior goes beyond merely acting on principle; the transition from principle to ideology takes place when someone decides that all others are just plain wrong.
Environmentalism as an ideology has given impetus to the new phenomenon of “Eco-Terrorism.”

You are talking Tomato, Tomatoes here.. Eco-Terrorism is as much an Ideology and Belief as is true Nazism. It is the direct belief that the world is wrong in a certain manner, therefore violent actions must be taken in order to change it.
