This should probably be just added to this thread , but I'll give you my opinion anyway.

When people say that they dislike this game because the main character has black skin, they're implying that they don't like the stereotypical aspects that come with it. They might assume that because the main character is black, the game will take more of a 'ghetto culture' direction and focus on the hard knock life, rather than the conquest of a city. That's just the way the world is. I don't disagree that Rockstar Games has even been advertising the cultural aspect of the game a bit too much and some people may be annoyed. This is why many people don't like the direction in which the game is headed, but I doubt that there is any serious racism involved at all.

just my 2 cents on the matter.. please do reply if you feel differently.
