Ironically, today blood quantum is not an imposed policy of the US government (although Canada still dictates enrollment criteria on many levels). It is an all too common policy of those Native peoples who have been reduced to "tribes, bands or nations of Indians subordinate to the United States" to punish, control, manipulate and eliminate their people by disenrollment or denied enrollment over pedigree. This has been driven by greed, entitlements and general abuse of power but leads to only one end; ours.
Many Native peoples have a range of methods to determining their identities, lineage and population. The Haudenosaunee and many others have a matrilineal system of identifying the distinction of peoples and family. The proverbial "you follow your mother" was the method to determine which clan and, specifically for the Haudenosaunee, which of the 49 families a person would identify as. This loose system is tens of thousands of years old and I say loose because the Haudenosaunee was always a culture of inclusion where adoption and absorption of peoples not physically born into these families was commonplace and a normal fact of life and would never be questioned.
But the "humanities" as determined by Greeks, Romans and Christians was built on hierarchies, class, and where individuals stood on the scales of civilization and human development. With Europeans came European ideas and influences. For the most part, the Haudenosaunee maintain the matrilineal system. Alienation has crept in other ways with the self righteous developing other means of exclusion but on blood quantum the Oneidas under the rule of their BIA recognized supreme leader Ray Halbritter stand alone.
Halbritter used some of the influential Onondaga icons to seize power as the sole leader of the "Oneida Indian Nation (OIN) of New York" back in the late 1980s. He then rewrote Oneida customs by crafting his official enrollment list of Oneidas (that list includes "Oneidas in good standing" and those who aren't). Along with his new list was his new list of enrollment requirements which include…, you guessed it, blood quantum.
Halbritter's ascendency to the OIN throne came with enough Onondaga Faithkeeper Lyons bidding that a complete departure from "tradition" would have looked bad so he kept a matrilineal component but put a blood quantum requirement of "Indian" blood at a minimum of 25%. Now some would say that is reasonable and, of course, IT IS NOT for a variety of reasons that will ultimately haunt all those who do such a thing but there are several problems with Ray's quarters. According to the unwritten OIN rulebook "Indian blood" can only come from a "federally recognized tribe." So in spite of the fact that more Haudenosaunee live north of the imaginary line between the US and Canada, NO Native ancestry counts for Halbritter's OIN. Of course, all of the non Fed Wrecked Native peoples are also not OIN recognized either.
Now add on to this arbitrary system of exclusion; politics, prejudice and "bad blood" and Oneida enrollment is just a game; a rigged game with bad consequences. Halbritter bursts on to the national stage as the "Redskin" slayer in a feeble attempt overshadow his failed handling of land claims, land title, gaming revenue and taxation while playing ethnic cleanser with his own version of "Bluebloods." There you go, Daniel Snyder, a name Halbritter would have to endorse.
Being Native is not about skin color or blood quantum. It is about being a people. It is about relationships, shared culture, language and distinction. While many Native people are concerned about loss of identity, rating each other by blood quantum is a fool's game. Dictating who the good Oneidas are and who the bad ones are or what is a "good Indian" forgets what Sheridan and so many others said: "The only good Indian is a dead Indian."
