TBF, it’s not hard to parrot Hitler. When they put emphasis on him being a former corporal, that’s because he behaved like a pretty mundane former corporal. Was a born orator, though, which is hard to attribute to Trump.
Now Goebbels himself was more dramatic and original and just as good an orator as Hitler. Which means he’s being regularly revisited by modern politicians for his efficiency, and not because of just being mundane.
