This is what boggles my mind, if you're a far right guy why would you chose Argentina of all places, thinking it is more libertarian than the US? You do realize the Argentine state is still prosecuting people that broke quarantine, and we had one of the longest lockdowns in the world, right? We also have tons of migrants (and you'd be one too, or did you only mean to call brown people migrants?), and Argentina is not gun friendly, so again, not sure where you're getting these ideas from, because Chile is much closer to what you're thinking of, but it's also more "ethnic" which you may not like.
The fact that the migrants flooding increasingly and completely uncontrollably into the US and Europe are 'brown' or 'ethnic' is of no importance except to racists ... and virtue signalers (often the same thing).
