The silly fellow is ignoring the fact that the people being kept out of UC Berkeley by AA policies are nearly all Asian, not white.
Talk about culturally based differences in SAT scores driving racial differences fails completely with Asians.
And then there is the problem with math - that Harvard study shows no culturally driven differences in math scores - does this not constitute an argument against AA in science and engineering majors ?
And I bet the alleged cultural differences in verbal scores found in that study are far smaller than would justify the degree of preference actually implemented.
Bingo!
