I always think it's rather a pity there isn't more than one human race, and that the Neanderthals and so forth had made it through. But we're stuck with only one, even if people make up fantasies about how different shades of skin means different races.

I can't see it lasting too much longer - if the human race as a whole survives, that is. No doubt we'll find some other reason for hating and despising each other.
