The Nazis weren't socialists. They were fascists. They used socialist language and rhetoric early in their rise to power because they knew socialism was popular in Europe at the time, and correctly figured that they would be more easily accepted if they were seen to embrace socialist ideals. That's also why they used the word Socialist in their movement's name. It was a manipulation of the populace.

Fascism is a far-right ideology while socialism is a far-left ideology. The actions of the Nazis were a pure reflection of fascism, and all subsequent fascist movements have been held up and judged against the Nazis.

There's a movement among some right-wing advocates to reframe Naziism as a left-wing movement, which is an absurdity. It's all about presenting themselves as pristine, and presenting the left as the undisputed bad guys throughout history.

It's historical revisionism intended to give talking points to the uneducated, anti-intellectual, and misinformed among their ranks, An attempt to rewrite history by pretending the Nazis were a left-wing organization when the plain fact is that fascism and Naziism were a far-right movement.
