I always thought people taking offense at the idea of evil being represented symbolicly with black as silly, the root of this is obvious and has nothing to do with race.
Human fear of the dark, because we have such a well developed sense of vision being robbed of it at night is frightening particularly to our ancestors who would have had nocturnal predators to fear, hence night and black (the abscence of light) become symbols of evil in many human cultures.
Sorry just an aside, I agree if they choose to change this or not won't make any difference to the game.
