I've been too simplistic re my comments on the NAZI party being a socialist party.
National Socialism was an alternative to Marxism and capitalism. The 1920 National Socialist Program - the "25 Points" - included demands such as the nationalization of industries, land reform and the abolition of unearned income.
Nazi socialism favored a technocratically- managed economy with the subordination of individual interests to the common good of the nation.
The Nazi government did not own the means of production, but it did exercise control over industries creating a managed economy.
The Nazi ideology also focused on the collective well being of the "German Volk" with a collectivists orientation - similar to socialism.
CLEARLY, Nazism evolved to essentially embodying the ideology and beliefs of one man and his Mein Kampf. That's where the German "living space" and hatred and extermination of the Jews moves to the front of the party's ideology. That's not really left or right ideology.
Bottom line is that Adolf Hitler's ideology is unique and a mixed bag unlike the Communists dictators I've listed.
Well, at least you did a bit of reading so I'll grant you that. But you're still pretty far off. I mean, there's a reason why there is tremendous agreement among scholars and historians on this topic.
1. For one thing, the "Volk" was not similar to socialism at all. It was the opposite. Marxism/communism was always considered to be a worldwide movement, across all cultures. That's why the communist anthem was called The Internationale. Socialism also had that same outlook (and same anthem) but to a slightly lesser degree.
Anyway, this difference accounts for the difference in militancy. The Soviets weren't actually interested in conquering for lebensraum. They were more likely to fund and assist in insurrectionary efforts, like Fidel's revolution and the establishment of a unified communist Vietnam. The Germans just invaded. The Soviets invaded Afghanistan for reasons that I don't understand, but obviously there was no domestic communist groups there to support.
2. The Soviets were not ethno-nationalists. In fact, they were quite the opposite: they rolled out the welcome mat for black people from America as well as colonized territories. Now, on the ground, there was racism because Europe had been fully racist for hundreds of years. But there was no idea anywhere in the Soviet ideology that some races or peoples were superior to others. Nor was there any idea that some people had to be expelled or kept out.
3. The Soviets did not have a murderous ideology. The gulag was for political dissidents and other enemies. It wasn't a concentration camp for all Jews.
4. Much of the Nazi party program was a rehash of various antisemitic ideas/grievances that had been floating around for a while. For instance, why do you think they opposed banking income? Because of the prominence of Jews in that business.
5. The Nazi ideology was wrapped up in the idea of a single leader who represented the will of the people. It was basically monarchy with a different grounding -- not divine right, but expression of the national will. Power was thought to bubble up, so to speak (not a historically accurate metaphor), from the German people but wielded in the singular figure of the Fuhrer.
There is no equivalent to that in any left wing thought I'm familiar with. For instance, Xi is not the ruler of China. He's the chairman of the Chinese Communist Party (you've probably heard of "Chairman Mao"). At various times and in various countries, that type of control has been more or less dictatorial, more or less subject to debate or disagreement. For instance, you probably don't know that Khrushchev repudiated Stalin, which would have been unthinkable in Nazi Germany. The transfer of power communist countries was never really familial until the fall of the USSR, except perhaps in minor outposts like North Korea.
And at the outset of communism in most countries, the early governments were meaningfully constrained "democratically." I put that in quotes because it wasn't a matter of voting, but it wasn't also not just one-man rule. For instance, the reason that Mao launched first the Hundred Flowers Movement and then Cultural Revolution was to purge the government of people loyal to communism rather than loyal to him. There was no such distinction in Nazi Germany.
It is not a close question whether fascism was left wing, right wing, or mixed. Every property that is a hallmark of right-wing thought was there in Nazism. The left has Stalin to answer for; y'all have Hitler. Difference is that we have rejected Stalin and you've embraced America's Hitler.
