I think it is close to a modern understanding of rasism, though an extreme variant: one race to rule them all. To rule or to genocide.

Hitler was not so much against Jews he was against non-Aryan people, the group that included Jews and Russians and African, and Asian, and almost everyone.

I'm not sure is it a good definition or not, but it is how it is. I vaguely suspect that this definition even may be offensive to Jews (judging by a recent Ruby Goldberg blooper), but honestly I have no intention to be offensive, just describing how it is. And trying to understand the other point of view.
