Do you consider it discrimination that disabled folks get to park in special spots? I don't consider discrimination. Some people just need more help to get where they're going, and some of us will be just fine using the legs we were born to walk with. In the same vein, I don't feel like I'm being discriminated against by affirmative action. And I'm not worried about my kid even if those policies remained in place.
Nobody thinks affirmative action is perfect. For example if I could make a change myself I'd focus on the economic part of socioeconomic more so that it's not mainly privileged people of color getting priority. But you have to start somewhere. With systems governing people it's just not that realistic to ask that everything be perfectly measurable or that there is a neat objective function to optimize.
> Therefore I am not phased by an argument that lists all the bad things that happened and concludes "oh you must still atone". And it is not justification outright for introducing discrimination to me or my children today.
You're very focused on yourself. Nobody is asking you as an individual to "atone" for anything because you didn't do anything. What we are discussing is _systemic changes_ designed to help folks who are disadvantaged _also without having done anything_. Broad, high-level changes like affirmative action just don't have the impact on individuals in the majority that you are making them out to have. They do however have outsized impact on folks in the minority.
In general I find it gross to be so focused on what you're calling your own discrimination when it totally pales in comparison to the experiences of folks who face actual discrimination. You say you're able to consider others' experiences compassionately, but that's clearly just lip service, otherwise you wouldn't be calling affirmative action "discrimination."
