Except that it's not the truth ... no schools do that for minority students. It's a strawman.
Having taught at UoM, I can say that unfortunately this translated to their performance on exams as well...

So yes, it's a strawman ... no schools do that anymore. Lots of schools never did it. And the schools that were doing so, were doing so with a fundamental misunderstanding of and in non-compliance with both the spirit and letter of the law.
Entering "minorities" and athletes enter with lower GPAs and SATs.
So? Surprise, surprise: when you start adding factors besides pre-college test scores to your admissions criteria you see ... variation in pre-college scores.
The methodology has changed. Now they use humans instead of a point system.
So you're unhappy that non SAT/GPA factors are taken into account. I'm curious if you've got the intellectual consistency to be in favor of simply ranking all students by their high school GPAs and SAT scores in descending order and taking the first N students. Maybe we don't actually need admissions committees or essays at all ...
