For those not sure of Native American US Status and Tribal Nations - here is a link to the Unrecognized Tribes and Native American Clubs all over the US. Many of these are of people who claim they are of Native Ancestries, but in many cases of these they just started their own "groups" instead of seeking out the actual Tribal Nations that their Ancestries are of, and learning completely what this means for their Ancestral Culture Heritages, they have grouped together with others, and now are in many cases trying to get status as "new/but old tribal nations". According to traditions of Nations actually acknowedged by the US and Canadian Governments, these ones are in many cases fraudulent. If they are of Ancestries it is their responsibilty to learn about thier actual nations, and become part of those nations. But because BQ (blood quantum) affects many of these ones negatively from being fully accepted for benefits (hunting rights, fishing rights, native scholarships, or even cash payouts from tribal nations with casinos, these "groups" will go after create their own groups in US and Canada and attempt to prove in court cases they are Native and demand same rights. This is literally cultural appropriation and theft from those whose families are still suffering on reservations, and its just wrong. (my own opinion & opinion of many on and off reservations)
