Except there is one key issue that you're leaving out here - that every good race is white and every bad race isn't. I mean, how often are the "barbarians" described as beautiful? The civilized race as ugly?

Edit: GMing Primeval Thule now, it's amazing how much difference it makes not to have any orcs/goblins/ogres in a setting. When the PCs kill people, almost always they are killing *people*. Even the Frazetta-Man 'Beastmen' Neanderthals who are explicitly the 'orcs of the setting' clearly have enough humanity in them to induce somewhat queasy feelings when they're slaughtered.
