I am going to go out on a limb and guess that his parents, grandparents and likely their parents were born and raised in Canada. At what point do the "colonists" become native inhabitants?
The Asians that colonized America were not all living together in perfect harmony, they attacked each other and occupied land belonging to other tribes. This was clearly documented in modern day Mexico as the Spanish rallied the oppressed populations that were conquered by other Native American nations to their side to overthrow the Aztecs and other Native American Empires.
Should we conduct further research to determine which tribes were the first to settle in a particular region, remove whoever is there now (even if it is another Native America tribe) and redistribute their land to the ones that first claimed it prior to any humans setting foot there?
This decolonization is going to get very complicated.
The point is, he has not been the victim of colonization, as he ignorantly (or a poor tongue in cheek crack) says it's not that bad, like the Africans colonized by Europe.
