I remember learning about this as a kid bc my parents stuck me in a lacrosse team. My mother used to go around introducing it to school kids and teaching them the history of it in PE class. At the time I just thought it was a cool tidbit of history but as an adult I look back at my team of sheltered suburban white kids with a touch of shame. I think what my mother did, teaching the history of the sport, was probably a good thing but it was history from the perspective of the colonizers. With the knowledge I now have of that genocide, I don't think I could look an indigenous person in the eyes and tell them I played "lacrosse".
I don't remember where I was going with this so I will post as is. It probably never had a point though, sometimes I just ramble
