Egoism is selfishness on principle, and the establishment really dislikes selfishness. So, quite consistently, they refuse to set one foot on a path that leads to it. But, you protest, everybody knows that only bad discrimination is under attack. I beg your pardon. When establishment spokescritters denounce discrimination, they mean what they say.
Racism is the chief pretext for the campaign against discrimination.
If that logic seems less than lucid, try to understand the establishment's problem. They hold that reason is invalid, that morality is arbitrary, and that collectivism is a moral ideal. Of course, it's no accident that they pick on discrimination. Discrimination implies standards, standards imply an objective code, and the establishment is committed to believe that morality is arbitrary. The campaign against discrimination comes straight from the establishment's basic ideas.
