Affirmative action in college admissions (or corporate diversity initiatives) give special consideration based on skin color. That's racist. If diversity were intended to be "socioeconomic" or "gender equity"(which would be sexist not racist) it wouldn't be racist, but in practice it's skin color. When someone asks if your student population or or town or workplace is diverse, they mean specifically 'do you have lots of different skin colors?' They don't care if you have a good mix of talents, backgrounds, and equally represented political views.
Affirmative action is attempting to fix past racism with more racism.
Systematic racism exists in the form of disparate impact (e.g. redlining from way back that trickles generationally), but it doesn't require anyone to drop out of school, join a gang, abandon a woman with child, or do any of the other things that lead people to difficult paths in life. Unfortunately these behaviors are most common in urban areas with large minority populations. Changing these destructive behaviors would do much more to fix racial inequity and disparate impact than affirmative action, BLM protests, or highlighting every white on black crime as racially motivated, or 'checking someone's privilege'.
Treat causes, not symptoms.
