I understand the anger, but man this isn't the way to go about things. BLM riots have headed north of the border.
Riots/arson are a tell-tale sign that people don't feel justice is being served, so they feel their only choice is to take matters into their own hands. Exactly the same happened with the BLM riots. The solution is to finally hold the churches accountable. The Catholic Church is a true piece of crap for so many reasons.
Violence is so inevitable in the face of such institutional intransigence it almost borders on appropriateness. I suspect the intransigence is born of the fear that indigenous people similarly abused around the planet will also demand accountability and reconciliation from past abusers. I hope and believe the inevitability of international systems of justice evolving to accommodate these indigenous aspirations will ultimately benefit all humanity. It'll take decades but a revolution is definitely on.
