I suspect Beyak is correct that there were decent and caring people involved in the residential school program, and probably there were students who did benefit from it.  

And one might be able to find examples of Nazis who were not malevolent, and dog and cat meat would provide a means of nutrition as well as correct the problem with strays.... 

But the overall narrative of the residential school program was its intent of cultural assimilation and there were far too many instances of neglect and malevolent abuse. 

Beyak may be technically correct, but is blatantly politically naive.
