I mean, racists 200 years ago knew that colonialism was a great injustice that would come back to haunt Europeans.
Johann Gottfried Herder directly confronted the nexus of European global domination and colonial violence, and suggested that history would have its revenge. "Europe must give compensation for the debts that it has incurred, make good the crimes that it has committed—not from choice but according to the very nature of things."
That was common sense more than 150 years ago.
That guy was wildly racist, yet he was also familiar with moral philosophy at the time and knew that colonialism was wrong.
To say that it is "about time" kind of obscures the fact that it has always been time and the subsequent fact that Europeans always ignored their responsibility because they could.
That is not going to change.
