Comment: You built your whole argument against putting native children in non-ntive foster homes on that generality: "some misguided settlers try to say that removing these children from their homes was a "good" thing, but this argument relies on the premise that getting sexually-abused by kindly settler foster parents was better than being sexually abused by bad Native parents."

No it does not, it relies on the premise that most will not be abused. Your premise relies on the assumption that most will. Which is/was a more reasonable premise?

The second part is still  unclear. That was precisely the objective of "the Scoop", to take children away from abusive conditions into nurturing ones. Either that doesn't work because it is too late, or we only hear about the failures, or about those who had the bad luck of getting abusive foster parents.
