This strategy of taking POC children and placing them with white families in order to anglicize them is much older than the current border issues. Canada has been doing this to native communities since at least the 1950s. They're just applying the same strategy to a different population.
I definitely don't want to derail this thread, and I definitely don't want to claim that this didn't happen, it did. Canada has some horrible shit in it's past regarding indigenous folks that we're going to have to answer for. Residential Schools, eugenics board, forced adoptions, it's all unbelievably awful and I know there's a tonne I'm leaving out.
That being said, the forced adoptions stopped in the 1980s, and the Government is at least making some steps towards reparations. That's not to say that there aren't still issues and systemic racism and abuse still happening in Canada, it's just to say that it's not a formal policy like we're seeing here.
Really not trying to be confrontational! Maybe I'm wrong, I don't know.
