That's where "diversity" arguments lead you. The real argument for bias toward disadvantaged groups is that discrimination in society leads to members of advantaged groups looking better on paper than they really are, and following the results of a biased system blindly would both predictably lead to a lower quality of student and recursively contribute to the original bias.
Separately: minorities face material discrimination at every income and wealth level. I understand that it's tough for some white people to support anything positive that they're left out of, but racial bias in college admissions is meant to be a counterbalance to other, negative things that white people were also left out of, at every income and wealth level.
But Asians were also suppressed by force of US law, and by angry, murderous mobs. If anything, they should be favored instead of pushed out, regardless of their level of achievement.
