Affirmative action doesn't come close to racism blacks and other minority groups experience.

Many people agree with you that affirmative action is racist, but that's the ONLY thing you can really point to as a white person, whereas actual victims of racism could point out new things on a daily basis. 

I'm not saying you should dismiss it. You should actually keep affirmative action in your mind as the only example of a racist policy you can understand as a white person. Minority groups face that kind of discrimination from multiple angles on a daily basis and have experienced collective atrocities in the past. 

Complaining about affirmative action is another textbook example of white privilege. "But I'm a victim too!" to which any actual victims of racism would just shake their head at you.
