There's a quick summary of the debate about accusations of racism in Resident Evil 5 here:
What do you think of the racism debate? I can see both sides of it, and I can understand how the Japanese developers really didn't understand why the game might be viewed as racist.
In their defence - they've blown away cities full of white American zombies, villages and castles full of European zombies, so when the game is set in Africa it's only natural that their characters will be blowing away hoardes of African zombies.
On the other side of things - some images have a cultural significance that is hard to avoid. A white gun mowing down black people is going to be incendiary for quite a while yet, and the transformation of the black population into mindless savages does feel a bit 19th Century in its representation of Africans.
... But should these kind of cultural sensitivities continue? If a white man hits a black man, or vice versa, on the street then it may have racist motivations, but the maybe longer that we think of racism as a significant cause of that kind of action then the longer it will continue?
Would the 1984-style of idea work, where removal of the language of racism from our knowledge-set actually remove racism too? If no child were taught about racism, then would it disappear in a generation? Or is the aversion to difference something that we must constantly educate people to overcome?
