Oh well let me toss in some citations anyway,,,
The typical definition of Indian tribe is 25 U.S.C. § 450b(e):
The term "Indian tribe" means any Indian tribe, band, nation, or other organized group or community, including an Alaska Native Village Corporation or Regional Corporation (as defined in or established pursuant to the Alaska Native Claims Settlement Act), which is recognized as eligible for the special programs and services provided by the United States to Indians because of their status as Indians.
The "Omnibus Budget Reconciliation Act of 1981," PL 97-35, August 13, 1981, introduced eligibility for community service block grants to state recognized tribes and tribal organizations. Section 674(c)(5) states:
The terms "Indian tribe" and "tribal organization" mean those tribes, bands, or other organized groups of Indians recognized in the State in which they reside or considered by the Secretary of the Interior to be an Indian tribe or an Indian organization for any purpose.
“express recognition” 45 C.F.R. § 96.44 (b) states:
The terms "Indian tribe" and "tribal organization" as used in the Reconciliation Act have the same meaning given such terms in section 4(b) and 4(c) of the Indian Self-Determination and Education Assistance Act (25 U.S.C. 450b). The terms also include organized groups of Indians that the State in which they reside has determined are Indian tribes. An organized group of Indians is eligible for direct funding based on State recognition if the State has expressly determined that the group is an Indian tribe. In addition, the statement of the State's chief executive officer verifying that a tribe is recognized by that State will also be sufficient to verify State recognition for the purpose of direct funding.
the Indian Arts and Crafts Act, 25 U.S.C. § 305e (d), introduced the term “state recognized tribe” into federal law.
So, like it or not,,, one can point out all of the things about culture that they want but the law is the law.
