I may be late to the party (apparently it was republished in 2016), but still a pretty good article if you haven't already read it. One thing it does not address, however, is the question of what triggers that something in people to become nazis. That is where I think the key lies. It is a work of years, to make them feel unwanted, unloved, unappreciated, and then get someone to uplift them. They will become as faithful as dogs, and, in my opinion, once we reach our breaking point, we all have it in us, so let's be careful.
