Blacks and Hispanics hate one another more than either hates whites. The reason is that they compete for the same niches in American society: the food stamp recipient niche, the teen single mother niche, the gang-banging hoodlum niche, the affirmative action (underqualified) student or employee niche, etc. No wonder there isn't much love lost between them.
In my experience blacks resent Hispanics while they hate whites; there is a difference. All of the freebies and affirmative action set them against each other, but they don’t have the history blacks and (some) whites had.
