Black Americans, like Jews, really do not want TRUE equality in the U.S. That would undermine their ability to play the race card from the position of a persecuted people.
Pretty much everyone else from every other race just wants society to move forward. But these two groups see that they can only take advantage of things if they manipulate how other people see them. They want you to ignore black criminals, worship black athletes and rappers instead. (Notice how no black person ever cared if OJ Simpson was guilty, they just wanted the black man to go free because the victims and accusers were white.) Brush Jewish political and media conspiracy under the rug, focus only on the tragedies of World War II. And so on.
Anyway, let the blacks complain all they want about zombies being shot in a GAME ABOUT SHOOTING ZOMBIES. It just dilutes their power to be taken seriously by the more rational people paying attention. Everyone can see that, at this point, blacks aren't fighting for equality any more. They are fighting for preferential treatment over Europeans, Latinos, Asians, and everyone else, in order to make up for their own cultural deficiencies. When they can grow up and play nice with everyone else, they will get the respect they want. Not one day sooner.
