You don't get it, they like the women, gays and non whites providing labor, they just want them hidden, so it doesn't ruins their gamer experience. They are just labor, and there is no place for them in the exclusive gamer space.
It's like the old days, you want your slaves and servants just to serve you, like machines, you don't want to acknowledge their existence as human beings. They are not equal to you, they just sustain your life style, because they deserve so. And only that, no humanity for them.
