It should be pointed out that had the Holocaust and WWII not happened, Nazi Germany was still an unmitigated nightmare that no one but the Nazis themselves were enjoying very much. There were and are plenty of authoritarian and fascist states where genocides don't happen, but which are nevertheless hell on earth for everyone who's not a functionary of the state.

So even if you think it's hyperbole to worry about extermination camps in the US, there's absolutely nothing hyperbolic about a dystopian state coming into existence in which dissent and difference are crimes. Donald Trump and his band of dead-eyed sadists like Stephen Miller will do whatever they can in a second Trump term to bring such a state to you.

Nazi comparisons are completely justified.
