There’s a perception in some circles that indigenous populations are more at risk of catching COVID-19 than the wider population so the priority to vaccinate them as a group is escalated. I don’t know however whether the risk is based on science or politics (and frankly don’t care - every democratic society is entitled to set its own priorities). Are you indulging in “resentment politics” yourself perhaps?
As your proud boast is that you evade paying Canadian taxes I’m not sure where that stands in terms of moral indignation.
