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.
Since national socialism ultimately developed from Bismarckian state socialism, I’d have to agree with the notion of reactionism at least. The original “battle for the soul of the nation” as it were.
