No, they were not.
But then, neither Trump nor his minions (not even Stephen Miller) were attempting, or suggesting deporting 15 to 30 million people, and empowering the police, national guard and military to achieve that.
Now maybe you don't seriously believe that Trump would attempt that - or you believe that our institutional constraints would stop him. But if we take him at his word, and assume his minions would treat those 15 to 30 million people the way they treated people detained at the border when he was in office (e.g., children in cages, camps in the desert, etc.)...then we're looking at detention facilities (OK, I won't call them concentration camps, for now) for literally millions of detainees in marginally human conditions, managed by people who see those detainees as sub-human animals. (That is what Donald Trump has repeatedly called them.)
Look, I agree that Donald Trump qualifies as "hapless and incompetent." But the people around him? There wouldn't be any more rational Republicans refusing to go along with his whims, blunting Trump's inanity. There would be the really nasty advisors -- Steve Bannon, Stephen Miller, Kash Patel, Heritage's Kevin Roberts, etc. -- pushing for destructive and inhumane policies.
Would it all rise to the level of Nazi Germany, or Stalin's Soviet Union? I hope not; but the reality is, nobody thought that the Nazis, or the Stalinists, would be that bad either... until they were.
Trump, and Vance, are deliberately stirring up out-group hatreds, with no concern about what that might lead to... and even if I discount Trump's intentions, there are people around Trump who we know intend to pursue chaos and/or anarchy - people whose goal, based on their own history and their own words, is the destruction of our institutions (and that's leaving aside any real influence that Vladimir Putin may have).
