Orwell had all sorts of fun with this nonsense in Animal Farm. He saw it in action within his former set of supposedly egalatarian socialists who turned out to be just as arrogant and oppressive as the aristocracy they ostensibly replaced; worse, actually, since within that aristocracy there were at least the restraints of tradition, however imperfectly observed.
This double standard is seemingly inseparable from what Marxists term class consciousness; it is, in fact, tribalism under another name, not socially progressive at all, but, in fact, profoundly regressive. All we're really hearing is a form of "four legs good, two legs bad."
