I'm an American of mostly German descent. I don't embrace nazi ideology and don't feel the need to. Anyone that embraces Nazi ideology does so because they agree with it.
Yes, very few people do embrace the Nazi ideology in this country. There are many people, however, who are race conscious here and Nazism does attract a few of them when they feel their ethnic group or identity are threatened. (There are some people who adopt the Hitlerian ideology from places like Japan and even Black Africa (!).) So it's not wholly race specific, but overwhelmingly Nazis are White, Northern European types, though, again, few in number.
