The real difference between Adolf and the commies was his rejection of their touted “internationalism”. Instead of a class struggle, his was a nation struggle with the Germans struggling against “inferior” peoples.
There’s even less difference between Mussolini’s version of fascism and communism.
I don’t dispute you, but I think one has to get the timeline correct. The Communist revolution in Russia was in 1917. This started Communist agitation throughout Europe. Hitler’s and other European governments were a reaction to that, I believe.
The Communist “intellectuals” in academia and the press don’t seem to want to get the order of events right.
