I mean even if they are, invading a country to stop the so called "nazi" and then occupy their land and take their child, is kinda like a nazi move. People who hate US doing this to multiple other country should immediately see how stupid the action are, but unfortunately tankie aren't very smart.

Marxism-Leninism-Zionism

tbf, one could theoretically have both. Nazis were down with Zionism insofar as it proposed to take all the Jews out of everywhere else and bring them to Palestine. Though they weren't wedded to Palestine; the Nazis also proposed Madagascar.

Politics, strange bedfellows, etc.

The bit where it gets strange is when you accuse a Jewish man of being a Nazi for the crime of (checks notes) wanting to reside in a country that isn't a Jewish ethnostate and has no plans to become one.

The reason why they use 'Nazi' is either because Nazi has stronger genocidal connotations, or because Russian propaganda pushes that anyone who opposes Russia as a Nazi, as the great crime of the Nazis to Russian ultranationalists is neither fascism nor genocide (else they might have to give a stern look to Great Leader Stalin) but opposing Glorious Mother Russia.

TBH I don't think national socialism is that closely linked to antisemitism. If someone does everything else like the German WW2 nazis but replaces hate against Jews with hate against any other mostly powerless minority, I think it's fair game to call that someone a nazi. Though in that sense a lot of people who often get called nazis still aren't nazis in a narrow sense, because their organizational structure and general ideology is too different.

On the other hand, it's usually just used as a shorthand/slur for "extreme rightwinger" (are those even necessarily fascist?), and IMO that's not that much of an issue.

A lot of modern antisemites see Israel as a solution to their problems.

You know why

Also nationalsocialism is inherently anti-Jew, therefore being nazi and zionist doesn’t really work out. Pick one or none, but you can’t have both.

It's not that the Nazis were anti-Jewish; many historical Zionists were anti-Jewish. It's that the Nazis preferred genocide through mass murder over genocide through mass deportation.

That is, strictly speaking, not true. Marx would be furious.
