How many of those diseases were introduced by the white man and had such devastating effects because the native population had no immunity to them? So what you're saying is that it was okay that the children died in the white-imposed residential schools because it took them away from death from white-introduced illnesses at home?? Well, that's a relief - I'm sure that was a great consolation to them on their deathbeds.
What about those that died at the residential schools as a result of beatings, sexual assaults and malnutrition - all, by the way, inflicted on them by the "high;y religious people" who ran the schools?
