"UC Berkeley sociologist G. Cristina Mora writes that, before government classification, there had been a “consistent empirical finding” that “Mexican Americans, Puerto Ricans, and Cuban Americans overwhelmingly considered themselves to be separate groups. They ‘didn’t really identify’ with one another, and they ‘didn’t really know what Hispanic meant!’”"
The categories "white" and "black" are also fully artificial categories, invented for political convenience. Racial-envy warfare trumps class-envy warfare, because nobody can imagine changing to a differ race. (Except Dolezal, I guess.)
This is the sort of thing which government status dominance causes. Entirely fraudulent submission. Or should I call it submission to fraud?
