I think they just really aren't smart enough to have their own framework about race, their retard ancestors never ventured far from their homeland so they never had to consider it. They're basically savages who have been forced to confront a superior species in just the past few centuries, relatively short on a historical or biological timeline. White people have advanced racial ideas because we've been explorers, conquerors, and travelers since antiquity. Also we're not retarded shiteating inbreds.
