What was the most important distinction between Naziism and leftism? You never quite say. And how were the Nazis or fascists of any kind, even remotely like what we call the right today? The only significant difference I can see between Naziism and communism is the communist wanted to take over the world so they could run everyone's life while the Nazis wanted to take over the world so Germans could run everyone's life.
I did so:
Letting big business run wild and idolizing the captains of industry isn't exactly "leftist." Nazis idolized a small governing elite, communists didn't do thisThe Nazi economy was very different than the economy in Soviet Russia (and economics are at the heart of the difference between Naziism and Marxist-Leninist philosophy). On balance, the Nazis were more "left" than "right," but only if you are an anti-collectivist right-winger. Conservatives advocating order and big business are closer to Nazis than leftists advocating social welfare programs and vegetarianism.
