I’d say this is a case of her just being stupid, not “insidious.” It’s also an example of how stupid a lot intersectional arguments are. Nazi ideology did not view the world from a perspective of whiteness or white supremacy. They viewed the world as separated by those who were Aryan - superior man, most intelligent, etc - and non-Aryans. Which included a whole lot of “white people” like Jews and Slavs (Russia).
Nazis literally believed Jews, black people, Slavs, and gypsies were subhuman compared to the euro centric Aryan race. So yes it was about race…just not race in the American sense (all white people on one side, all black people on another side, etc). Hell this is more like fantasy world concepts of race where you have humans as one race and elves as another race.
