First of all, do not attempt to insult any of my friends.
If you expect me to have a respectful discussion with you then do not insult my friend. I will not tolerate that kind of behavior.
Secondly, it is not possible to “get over the past” while Native peoples from South America to Canada are being oppressed, being victims of genocide, segregation, poverty, hunger, rape, and violence. This war never ended; settlers merely found a way to live with averted eyes.
