The Nazis and the Communists were essentially the same, differing for the most part on whether to have a national or international agenda. One of Hitler’s early aggravations was that the Communists already had dibs on the red shirts.
They fought over their common base more than ideology. And the winner eliminated the loser once they were in a position to do so.
The Nazis were a left-wing political movement, don’t let anybody tell you otherwise.
That’s an endlessly debatable conclusion but if you want to say the NSDAP was “left wing” be my guest.I don’t know that we can compare the left and right of today with early 20th century German political movements. The “reds” of those days owed allegiance to USSR communism whereas NSDAP was very pan German. Today we have a democrat party dedicated to god knows what but it ain’t America. If NSDAP was “left” then communists were much further left.
