Race has ongoing salience. It continues to affect the opportunity structure. To say that colleges should be deliberately blind to do that is to say that they should be blind to discrimination, to stereotype threat, to what it is like to grow up and face daily dehumanization.
The effect of the policies should not be massive and should be defensible by statistics and means-tested efforts. And it should be accompanied by class-based affirmative action. But race should be considered directly as a variable.
