       | Reading this and the talk about how "surprising" it is reminds me
       | of how I've been researching British Columbia's relationship with
       | First Nations people, and this research extended to other people
       | in the Pacific Northwest under the US system.
       | 
       | My takeaway is that everything about this is heavily
       | misunderstood.
       | 
       | As CPG Grey also concluded, the entire concept is overinclusive,
       | to its detriment. As we squabble between terms like indigenous,
       | First Nations, native American, Indian, we are missing that these
       | are all distinct cultures and there is no overarching grouping
       | really possible. Each distinct group has its own name, own
       | customs, _own case law_ and enjoyed its own sovereignty at one
       | point, and should be addressed by the name of their people, at
       | the same standard we distinguish people by country or religion.
       | 
       | British Columbia is uniquely addressing this, with rights
       | conveyances group by group. But it is a very long way from being
       | closer to accurate. I think accelerating this relies on non First
       | Nations people understanding that there is no overarching term
       | possible (I dare say, including "First Nations") and that the map
       | of North America should be dotted with microstates just like
       | Europe is

         | people of northern BC don't want to be cut off from the claims
         | in the south, the claims involving the most valuable lands.
         | 
         | BC, and Canada more widely, is struggling to determine who
         | should even be at the table to negotiate. Traditional
         | territories overlap. Blood claims are often based on shaky
         | evidence. Something as slim as a single forged letter can
         | expand or contract a community by thousands. If treaties or
         | settlements are going to be signed, by who? Are the people in
         | charge of various groups today in any better position to sign
         | permanent deals than their ancestors were a few hundred years
