They are changing not from some incidental organic pattern of behaviour, but by a enforced immigration that many Canadians want to see drastically reduced. As for the SA/NA indigenous in the 1500s+ their civilization were, and I don’t mean this disparagingly, Stone aged tribes. They were conquered by the Europeans in the same way that they had conquered one another’s tribes for millennia. I would also point out that they fought like warriors defending what was theirs. Supplanting current White Canadians with a never ending wave of immigration to enforce “diversity/multiculturalism” is suicide from within by a ideologically authoritarian government.
