You're quite right, and unfortunately, just as almost everyone group has been glorified as "superior" by some of its members, a lot of groups have also been demonized, with the Germans being an obvious example. And yes, I've often corrected people who said that "the Germans" did this or that, or "the Japanese" did this, or "the Russians" did that. I know I don't want to be blamed for all the stupid and/or evil stuff that has been done by other Americans, particularly those who wield political "authority." I've also been happy to see a rather significant number of Germans getting on board the voluntaryism wagon.
