I’m Canadian and Canada is part of the continent you’re talking about. I can’t go anywhere without running into indigenous people I know personally. Canada’s program of ethnic cleansing was several levels deeper than the United States but indigenous people are all over. Demographics suggest they will be the majority in my province before I die.

You seem to be... bragging about? or at least seeking recognition for? your country's policy of forced assimilation vs. another country's policy of forced removal.
Aside from being a deeply weird thing to say, there's no buffalo left in either case.
