If you are worried about Nazism, or fascism, I have a vaccine for that. It’s the same one that our parent’s generation used to great effect. I’m afraid that you won’t like it though. Ready?
Get involved in public education somehow at some level. Demand that Rhetoric, History, and Critical Thinking are taught as *mandatory* classes once again at the high school level. Let the School boards worry about something other than ‘if bare midriff shirts are disruptive.’
You see, the Constitutional Founders had faith that if the public was well-educated they wouldn’t be attracted to puerile philosophies like Nazism. It turns out to be true. The bad thing, by some reckoning, is that they aren’t attracted to puerile philosophies like Capitalism or Communism either. A well- educated, literate population is rascally like that.
