Just got solicited on the phone by some Arizona tribe to give them money to take care of their elderly. When I kindly informed them that tribal law is an offense to the ideals of equality, justice and freedom, and that I would only be willing to aid them in their plight if they disbanded their tribal government and became equal citizens under U.S. law, well, they decided that conversation wasn't going well for them.
Good times :)
Update: looks like this is a typical tribal scam: http://www.citizensalliance.org/links/pages/articles%20and%20CERA%20news/Questionable%20Indian%20Charities.htm
