Not so sure he hated communisim. I think he hated Russia.
I guess he coulda hated communism too.
Hitler did not hate communism, he hated Marxism because he hated Russians. The NAZI Party was National Socialists plain and simple. Socialism or it’s other name communism, is the same side of the same coin just minted in a different alloy. Both are always used as the first emotional step to totalitarianism.
Like most totalitarian, the National Socialists hated competition.
