Ah, yeah, because depriving the overwhelming majority of inhabitants of any say or sway over the place they lived worked so well the first time we should do it again. Or were you planning to let evil settlers have a say in indigenous government (in which case it is indigenous in name only)?
Fixing a wrong with another wrong has a long and proud history of producing more wrongs and no rights. The abolishment of Canada may well be necessary, but if we're not going to make things worse, we need a solution based on the reality of what did hapoen and what the situation is now, going forward from there; not on the ideal of what we wish had or hadn't been done in the five centuries before,mor trying to take back history.
As to Akka's eyeroll-worthy little comment, I will point out that annexing vast territories full of people who outnumber you by a lot, along with their existing political structures and fully settled social systems is not meaningfully comparable to taking in refugees or anything of the sort, and otherwise not further engage with the nonsense.
