MegaWarp has an article that examines the various complaints about the supposed obnoxious racism and sexism in games.
"There was criticism about Resident Evil 5's abundance of native African zombies. This complaint is actually entirely baseless.
Since Resident Evil 5 takes place in Africa it makes perfect sense that the zombies are predominately of native black-African lineage.
Games in general are not all down-to-earth and usually stretch people's imagination.
Improving the overall quality of video games and entertainment in general is not merely adding lots of minorities with unbelievable role mixing. People should not get preferential treatment if they have ethnic-minority or gender status (the minority is actually the majority), because this by itself creates discrimination and sexism. Big government and representative organizations should not meddle or dictate the content of entertainment."
