The problem is that many of the grievances are self inflicted or illusions and as such are unappeasable and un-negotiable. 
Well meaning left wing journalists are not helping the First Nations or Canada by failing to confront these illusions and feeding them.  Likewise the government of Canada.  When you feed a delusional mans illusions you heighten the stakes and increase the likelihood of violent outburst.
It's a high price to feed to ones righteous self perception - ones vanity.
