>>WW2 wasn’t started by a communist or socialist, but by a Nazi,
The response to that is “You mean the National Socialists? And make no mistake about it, the NSDAP platform has many elements in common with that of the Democrats.”
I always tell them that nazism is nothing more than a distilled form of fascism, a subset of socialism. Fascism tied the love of one’s country and Nazism distilled it further to the love of one’s race.
