I notice this alot in the black community.
People making fun of others for being "too dark", or having "nappy hair"...its absolutely ridiculous.
Some even go as far as to ADMIT mental inferiority with comments like "Whites got book smarts, we got street smarts" or "Whites do good in school but we are better athletes".
Self hating nonsense.
"Criticism must be sharp… If you do not do things well, I won't be satisfied with it, and if I offend you, I offend you, and that's that. To be afraid of offending people is nothing more than being afraid of losing votes and being afraid of having difficult relations in one's work with one's co-workers. Will I starve if you don't vote for me? Nothing of the sort. Actually, relations will be smoother if you speak out and put the problem clearly on the table… A bull has two horns because it has to fight. One purpose is for defense and another purpose is for offence. I have often asked comrades, Have you grown any horns on your head?' You comrades can feel your heads and see… I think that it's better to grow two horns,' because that conforms to Marxism" - Mao
