Hitler was the classic Socialist, just like Stalin, Mao and Pol Pot, and they all had strong threads of Nationalism and racism in their dictatorships as well.
My point is that Socialism + Power = Totalitarianism.
I laughed at your “ Socialism is international, it’s one of its core values!” — that is so phony: that is only rhetoric for the indoctrination of naive and idealistic young people. It is as fake as the dictatorship of the Proletariat fading away once capitalism is defeated. That never happens either.
It is important that people understand that all Socialist one-party governments will act like Hitler’s Nazis: Stalin, Mao and Pol Pot are acknowledged as Socialists, but Hitler is not.
It baffles me how generations of children have been taught that Hitler is Right-Wing, rather than the Left-Wing Dictator he clearly was. Perhaps the preponderance of Socialists in the Teaching profession has something to do with it. It is the ultimate Big Lie, to quote Goebbels.
I understand that it is far easier for you to believe that Hitler was a Fascist, but that is Fake News, the ultimate straw men’s argument.
