What's particularly interesting to me is the tension between a) promoting a more open democratic process, especially among young people and b) preserving Navajo language and culture. Both are generally good ideas, but here we see them come into conflict. Ultimately, as an outsider I see this as a good thing, based largely on the following quote:
"It discourages Navajos who are educated and live off the reservation to return and help their people," said Teller, 36.
But even though Dine is the native American language with the most speakers, I do very much sympathize with people who feel this might adversely affect its long-term survival.
