A society with severe imbalances in wealth, health, and power should examine how those imbalances came about. If it turns out that they're directly caused by racism, that society should consider race-conscious remedies. This is true regardless of how long the racist policies have been perpetuated, and it's true regardless of whether or not the federal government of the USA still exists.
My only disagreement was with the conclusion that such remedies should be ordained at this moment to be "always be a topic deserving of special dispensation" since always is a very/infinitely long time.
You design one for its ever-lasting nature.
You design the other to achieve a specific outcome.
Reminder that even the oldest of official policies in the US are just over 300 years old. Two magnitudes less. Most policies currently in use are less than a hundred years old and are a result of changes and amendments to those that proceeded them.
Even common law is only a thousand years old and has been revised over time.
None of that has anything to do with the issue still being relevant now and for the foreseeable future, ie the colloquial definition of “always”. When that eventually changes, then it can be re-evaluated, but that’s not likely to happen within our lifetimes, so it should very much be remembered when policies are made.
If white supremacy would stop being perpetuated, we could stop worrying about the effects of white supremacy. But the discussion doesn't have to end after a specific timeframe just because you feel uncomfortable with it.
