Wait, sorry, what? I've been following along here, and my take is roughly akin to MB's. I do not treat people differently based on their skin color or ethnicity. My goal and hope for the world is for everyone to ignore skin color and ethnicity. If, as you say, AA is not racist because its goal is zero racial discrimination, then it follows that I am not racist either by the same standard.
Is it? Because you won't get there. Some people may feel they are pursuing a goal, except that their way of pursuing it will never achieve that goal.
This is one of those cases.
White people have a head start over black people. That's just the history of the US. And it remains current now. It's not like the current US climate is free of racism or the effects of past racism. It is something felt every day. The fact that many have largely overcome it does not mean that it does not present obstacles that many other haven't been able to overcome.
So you have all these obstacles that many haven't been able to overcome without help. And many of the ones who have overcome did have help. Now you remove the help. Where does that leave you? You haven't removed the head start that whites have. You haven't removed the obstacles that blacks face that whites do not face.
You want a society where "everyone to ignore skin color and ethnicity", you have to be willing to work to make it happen. Choosing to do nothing is choosing to be certain that it does not happen. Not in the foreseeable future, at any rate. The rate at which these things happen on their own is very, very, slow. If ever.
If you want to just stand back and see if the problem will go away on its own. And not take any steps to make that happen, not not mitigate the obstacles that were deliberately placed to prevent it, not mitigate the historical circumstances that make it far more difficult to overcome, not undo any of the damage that has been done, that continues to be done on a day to day basis, that just is not color blind.
Personal responsibility does not say "Oh, maybe they do face all these extra obstacles we've placed in their path, but it's not our responsibility to help them. They have to take responsibility for themselves." No, that's not personal responsibility. Personal responsibility says "I have benefited at their expense, I owe some mitigation or remediation of that harm done to them".
As a mitigation or remediation, AA is trivial.
