Rob, I'm glad you chose to ask first. That's a good sign. The general policy for this board is that we ask that you ask any individual board member for the right to repost their posts or use them elsewhere. Each person has (or should, in an ideal world) the final say in where their words wind up. A few like myself have said many times that anyone is welcome to use their words anywhere it will do any good.
But I really have to wonder.... It seems your hope is to try to get through to the parents through what their kids learn and pass along. A lot of Nuagers see only what they wish to see, and often filter out or worse, misuse what they've learned, learn in effect to be more subtle or effective exploiters.
I'm not trying to discourage you, only prepare you for a different outcome than what you might expect. Don't be surprised, for example, to hear "He's only one Indian, the rest are different, he's an extremist, an outcast, a racist, I bet he's not fullblood, not a pipecarrier, not a REAL one you know", etc. Quoting from a wide variety of speakers might get you better results.
Where is this, I wonder, where "a lot" are into neo/pseudo shamanism?
I know Trish's site used to have a list of quotes from many NDN leaders about Nuage, from Deloria, Oren Lyons, Wendy Rose, etc. Does anyone have a link to it?
