If you’re interested in this topic, I really recommend reading How Fascism Works, by Jason Stanley. [1] It’s a remarkable book - slim, easy to read, and enlightening. What was most astonishing to me was that there is a playbook: ever wonder why these regimes always target LGTBQ people, for example? It’s explained here, along with everything else you need to know about the mechanics of prosaic, predictable type of government.
> According to a New York Times review, Stanley's book—a "slim volume"—"breezes across decades and continents" and says that Donald Trump "resembles other purveyors of authoritarian ultranationalism."
