I get that it doesn't make sense to require every admitted at Harvard plays the Violin/Cello. But it's easy to discriminate against a minority--like Asians--with facially neutral quotas that are designed to exclude them. "We've already got too many classical music instrument players" when the admissions dean knows Asians are more likely to play those instruments.

Schools in state's that banned affirmative action still practice it by applying these standards.

If racial discrimination is acceptable in this case, why not other cases?
