I think (as a white non-american) that there is a difference between seeing race-blindness as the ultimate goal - which is not yet archieved and won't be for the foreseeable future - or seeing race-blindness as an explicit non-goal.

I think the OP is arguing for the first variant. My impression is, current anti-racism/identity movements are more advocating the second variant and are emphasizing blacks and whites as fundamentally separate groups, which cannot and should not be reconciled.

If this is really the case, I believe this is some major shift of objective - and I'm honestly puzzled what the "ideal society" that we should work towards would actually be in the second case.

There is also a difference between past atrocities which must be made up in some form and discrimination that continues in the present. I agree that the history of slavery and genocide in the history of american settlers is far from being appropriately processed. This is something that must be taught in schools and attempts to make up for the evils must be made - maybe even as some form of reparations, though I have no idea how that could work in practice.

However, it's also clear you cannot punish persons that live today and had no choice about whether or not those atrocities took place.

I think more talk between black and white people about some kind of positive vision of the future that all could work towards for would be more constructive - if it's possible at all to build such a vision.
