OK, so there is no answer as to what "Person of Color" means, or at least you can't or won't define the term. Even though you used it in your initial post. So it means what it means to each person, which means that it is a gratuitous, meaningless term. Employed gratuitously by people of all ancestries, not just by "People of White", as you put it. Check out the popular press, radio, and particularly the talking heads on TV.

As for racism, and all that it spawns, it is pervasive in human cultures, of European origins or otherwise. That applies equally to Alaska, and pre-contact pre-Alaska. It doesn't take much digging to disclose this, just an open mind.

That is not to say that racism is either good or acceptable, nor that societies should not strive to eliminate it. But to insist that it is the franchise of one genetic group is, I'm afraid, racist.
