I don't feel easy with the vilification of patriotism. Such feelings grow from the natural instincts of people who feel affinity with those from their own culture and who wish to defend their homes. Any harm done happens when sociopaths exploit such feelings for their own cruel ambitions.

Or are people knee-jerking when they see text including "Nazi" that isn't one dimensionally negative throughout. Please point out the text that is apologizing for their behavior. I am only dispassionately discussing the details of of who they were and their social context.
It's not the comic book evil of the Nazis that is the most striking thing about that whole sad chapter of human history. It's the banality. We're much better served by thinking of them as people and seeing the details of how they got the world into horrific war than to merely caricature them. We're much better served by taking history's lessons to heart and acknowledging our own horrible potential.
