I'm not sure if acknowledgement will actually change anything. It's something that bears mention, but the rabbit hole is so deep that I am unsure if there would be anything that could be done to undo it. It went on for centuries, those who thought to try and stop it also played right into the conspiracy, and now there are so few indigenous people that anything that we try is a worthless platitude. Everything we can think of is worth doing, but even all of it wouldn't make up for what was done long before now.
