It’s a waste of time to discuss affirmative action for URMs in this context. Either you support it or you don’t. By itself, it shouldn’t affect Asian students any more than it affects white students. I suppose that if eliminating affirmative action benefits Asians at a higher rate at some schools than it does white students, that could be some statistical evidence that white enrollment was being supported at the expense of Asians. But without some kind of smoking gun evidence of discriminatory intent, that kind of statistical evidence doesn’t get you too far.
Anyway, affirmative action for URMs remains lawful for private selective schools (like Princeton) as long as they jump through the proper hoops, and the OCR report shows that they are jumping through those hoops. If you don’t like that, you’ll have to change the hoops.
As for the question of whether selective schools are discriminating against Asians in favor of whites, where do people who believe this go next? I don’t know. I think they will face the same results at Harvard, and at any other selective school.
