But even among the fundamentalists the vast majority are not violent. They may violate the treaty and deserve no tolerance under it, but since they use politics to do so - they can be fought with politics and this should always be the preferred way.

A small minority though - take it a step further, they will slaughter you for whatever they believe in. You can think of 9/11 or Dylan Roof here - all examples of the same thing.

And Nazis -they are in that category, becoming a Nazi is no different from joining Al Qaeda in terms of what it means for everybody else. You are - from then on - an enemy combatant.

While there are many groups like that however, none are a graver threat than Nazis. No other group has ever come close to achieving the terror they have inflicted. 

Al Qaeda has killed less than 15-thousand people in their entire existence. The Nazis at their peak were doing that in a day.

That's the point here. We're talking about the most dangerous terrorists in history.
