The thing is, there are just groups of professional agitators who have nothing better to do than go about crying, "Racism!" whenever they feel like it. Plus, subconsciously, a lot of white people are terrified of being perceived of as racist (by other white people), so, if they see something that triggers their racism alarm, they'll call it out so as to appear less racist, whether it's relevant or not.
Plus, people don't take into account that different parts of the world have different experiences with race than America. I mean, in Japan, racism isn't necessarily an issue they give as much thought to, not because they're a racist society, but because they don't have that history with racism, so they don't think about it the way Americans do. They never had African slavery, and they don't have a large disadvantaged community of black people in their country, so, when they designed RE5, they were thinking, "This is a zombie game set in Africa with an American protagonist." They weren't thinking, "This is a game where a white guy shoots black people."
People in different parts of the world don't seem to think about race the same way Americans do. It's more about nationality than anything else. It's like, if you're Dutch, you're Dutch, and it doesn't matter if you're black, brown, green, purple, or whatever. There's no such thing as 'African-Dutch'. There's no hyphen there. I guess that's just to do with having a different historical experience with racial issues...
