well, that's the rub with racism and persecution right? It's a very subjective and emotional thing... how can you say to someone who isn't black, or what have you, that what they're experiencing is not racism just because their skin color doesn't match a particular shade?
In any event, I think context is key... I don't think capcom game designers have any incentive to continue american style european versus african racism... I would imagine, rather, they are resonding to the current situations in areas like dafur and not so long ago, sierra leone.
anyways, I've been in way too many OT debates recently, so I'll say no more on this. But there are quite a few good blogs out there that deal with this subject matter.
