As you might expect the reporting lacks all context. This was (with the usual s**t stirrers thrown in) overwhelmingly about over 1,000 First Nation kids’ unmarked graves being found in three residential schools to which they were forcibly taken in less enlightened times.
I wouldn’t begin to defend the original policy but some of these graves are 150+ yrs old and the deaths were broadly known about from various real epidemics. It’s now more about First Nation land rights and historical appropriation and other grievances. Many are probably justified.
You don’t need to go to Canada though. The same people were running horror houses in Ireland. The Vatican has yet to comment. Doubtless they will say it was ‘colonial’.
