Quick and dirty...
Hitler was a fan of private industry, was privatizing public holdings all through the 1930s, and was supporting private industry through the provision of slave labour through the 1940s until war's end.
The "socialist" in National Socialist was a populist ploy to pick up Socialist supporters in the early years of the party.
Had he been a proper capitalist, he would not have had such supply chain management issues and his Army would have survived that disastrous winter on the Russian front. Stalingrad would have fallen. Socialists can’t do anything right
Problems with the supply line to Stalingrad had nothing to do with socialism and everything to do with poor planning and long distance. The Russians had a scorched earth policy toward anything useful they couldn't take with them as they strategically pulled back; the Sixth Army, aside from pockets of heavy resistance and surprise landmine hot spots, had to contend with burned out crops and hamlets. The Russians left nothing the Germans could use - so they had to rely almost solely  on the ever lengthening supply train. It was a simple matter for the Russians to cut that line. And there's no guarantee Stalingrad would have fallen at any rate. JB is grossly underestimating the Russians.
Being a Nazi, much like being a Muslim, is far more than just a set of ideas about how to structure society. It’s ultimately about annihilation. The complete and utter destruction of the weak, the....This is not based on some sort of preference derived purely from aesthetics. That’s nonsense. It is settled science that height and weight and the amount of melanin in your body is correlated with intelligence, accomplishment, leadership ability and just general superiority.
This has about as much scientific weight as phrenology.  I remember watching the 1936 Olympics. Seeing Jesse Owens dominate in his field...that turned Nazi science on its head. Or, if JB wants to talk race science, why do Asians consistently outperform whites on IQ tests?
The Nazis didn't know about DNA or epigenetics. They had a 19th Century understanding of heredity.
But JB is certainly right about one thing: People toss around the term "Nazi" too casually.  It has a specific meaning.
