There's a slight conflation of ideas here. The Nazis wre demonstrably wrong about things other than just their moral worldview (I happen to agree with Miles here, vaguely and approximately, and am really turned off by the Rortyesque "the Western liberal as moral yardstick" line). The Nazis believed in a racially defined humanity in which angelic Aryans were besieged by satanic Untermenschen. That's wrong just as a statement of fact. It was a paranoid fantasy that became translated into politics. They were wrong in a much different sense than, say, people who believe that slavery is justifiable (which is most people in the "civilized" world before around 1800).
^^^^^ CB: Rationalization of the African slave trade was based on fantasies as factually wrong as the Nazis' fantasies.
