> That's true, but I still wouldn't call the average (neo)nazi's world view "consistent". They believe(d) jews owned the world, that white men came from the lost continent of Hyperborea, that communists were allied to the jews in an international plot to undermine the "white race".
> There are many reasons one would fall for such falsehoods, but I don't think reasoning your way into a twisted ethical paradigm is one of them. In other words, I think you have to reject rationality and reasoning altogether to get to this point.
I think you're conflating fringe myths with the actual core ideology. The leadership's principles were coherent, even if built on lies. People don't need to reject rationality to fall for it, they just need to rationalize cruelty within a warped framework.
> They act purely out of a desire to fit into the in-group.
That's pretty reductive don't you think? Though warped and morally indefensible, they definitely have defining principles. It's unwise to treat your ideological enemies introspect and intellect as inherently inferior to what you perceive as your own.
> [...] there was no inherent predisposition to nazism, anyone can, under the wrong circumstances, fall into that.
I get the point, but I don’t buy the 'anyone' angle. Some people just aren't predisposed to that kind of thinking or behavior, no matter the environment.
