The whole blood quantum aspect is screwed up, and a means in which the government continues to keep Natives down. It is horrible when you really think about it. No other race has to go through this. That's why most tribes don't give a flying **** what your DNA test says. If you can prove connection to someone on one of their rolls, you are Native. If not, you will not be recognized (in most cases). It is an attempt to reclaim control over this in some small way and reduce the internal damage and strife caused by the whole concept of blood quantum. The only frustrating aspect is how hard it is to prove that connection under so many different circumstances (for one, it was worse to be identified as Native than absolutely anything else). I have tested as high as 21% on a chromosomal level (which is by far high enough to be considered Native in that regard), and because of a massacre that resulted in a "secret" adoption, I have yet to be able to make the necessary connection to a roll.
