Okay, so you want to think that it's racist fair enough.
What if it was a black man with a white woman, walking through some European place killing white people? Would that suit you more your majesty? Or what if all games featured just 1 race? Then they'd only be killing themselves, would that please you oh great one?
But oh, wait. If there was just going to be 1 race, who would it be? Would it be just white people? No! Of course not, that's racist. Well okay, would it be just black people? Black people killing themselves?? That's related to gangs!!! ARE YOU SAYING ALL BLACK PEOPLE ARE IN GANGS?!?!.. No..okay, just black people are out of the picture. And same goes for all other races and religions.
No matter which way you look at it, it will be racist to someone somewhere no matter what race/religion is featured in the game.
So I guess Call of Duty 4 is the devil? Those terrorists killing those Americans (and visa-versa). I think you're right, everyone should just close there eyes, sit down and not look at anyone or interact with anyone or anything in any way ever again because - it just may be racist.
