AA IS racial discrimination, make no mistake. As such it has a number of problems, chiefest being that it allows underqualified persons to be accepted to colleges or job positions because they are a minority. No matter how much you want to take the responsibility for what you ancestors, or ancestors of other people in the country, did to Africans, the fact of the matter is that discriminating to alleviate disparities helps no one. Eliminate the socioeconomic difference between minorities, and the educational differnece will disappear. Leave it in place, and nothing you do to fix the symptoms will have any effect on the underlying problem.
