"How is academic ability different from athletic ability"
'Many students support affirmative action, in an effort to promote diversity. They argue that race-based preferences “level the playing field” for disadvantaged minorities. However, these same students refused to sign our petition to apply such policies to the basketball team. At UC Riverside — where the video was filmed — 10/11 active players on the team are African American. Why not use affirmative action to promote diversity there? '

The Exposing Leftists website makes some good points.
