If we didn't have races, we have genders, or religions, or nationalities, or height, or weight .... If we didn't have those, we'd have "Let That Be Your Last Battlefield."

Yeah, there is that. As if they're ashamed of actually saying "I want to be top dog and have all the toys." And I understand that it's just evolution, the fear of the other, but for people who, by and large, don't even believe in evolution, they sure as hell buy into the idea.
