Comrade, I am talking about the implications of a meme. Not social insulation. Racism persists because dominating others by race is convenient and profitable, otherwise the racist looks like a loon to the crowds. Race and cultures are commodities for the exploitation class.

Playing games to simulate commodifying races for amusement is what I am emphasizing. The former characters, as homogeneous, one cannot read or commodify their race for amusement, unlike the latter two which do.
