Wondering because when I hear people compare the Trump administration to the Nazi party, and how people are saying "oh this is gonna turn into the Nazis all over again"... when the Nazis were beginning to rise were people thinking "oh this is gonna turn into __ all over again?"
And who was the "you're being literally like Hitler" before Hitler?
