@Earthbound_Misfit No one would be forced to be a citizen, this is about right of return the way I understand. Same as I’m not Israeli, but if I want to go live there I can under the right of return. Children and grandchildren of Italians who live outside of Italy can get Italian citizenship with the needed documentation. Some countries are easier than others. Right now Mexicans who have family who lived on the Texas side in the 17 and 1800’s, but have never been citizens of the US in the last 100+ years, have no right to citizenship, because of the family history having been across the border for a time.
The indigenous people in your country have the choice, and are physically in your country. The OP is talking about people who might not even be physically here I think. If they are here, then I don’t see how they prove their families were here generations ago. Just being part of an Indian group would be a tough sell. The Mexicans are very mixed.
I do see your point though, and the OP’s point.
