I think you have a couple of different concepts going on at the same time.
First, when we use the word “indigenous”, we're talking about a lot of different people. What Camille is doing in her community, what Lynn is doing in hers, and what I'm doing in mine are very different. They're first nation and Métis.
I am Métis. Georgina and I even come from the same community. What she might have learned in her community is different from what I learned in my community.
Knowledge is passed down from generation to generation in families and in communities. You can be an outsider within the Métis community. If I go to Georgina's community, I'm an outsider in her community, so I have to be mindful of how I'm gathering that information.
