Discrimination against minorities by minorities

Minority bigotry
Active prejudice towards minority groups by other minorities
In the USA in 1994 it was reported that there was as much discrimination between the principal ethnic minority groups as between those groups and the majority.
The rise of black anti-semitism in the USA puts at stake the moral credibility of the black struggle against racism. And the general silence about rising black anti-semitism in the US helps make anti-Semitism respectable, pain-free and profitable. Jews in America must continue to fight against anti-Semitism with every weapon of persuasion of power at their command, except one -- to turn themselves into racists.
