Ok, '97 is impressive! I have two for you from our side:

• people were purchasing indigenous children forcibly taken from their parents as late as 1952
• Our federal indigenous school system shut down only 28 years earlier than your’s, and ours has a strong record of killing the children in its care. (Same report, two different articles).

I am aware of the Canadian atrocities; I still think the US wins this contest, though… again, Trail of Tears is kind of a trump card.
