Ariel,
I, too, am an "Indian". Specifically, I am of the Puyallup Nation, which is Coast Salish. I don't have a problem with the word "indian" simply because of its common usage. However, in a formal introduction I would introduce myself by name, nation and family lineage.
I appreciate you not wishing to sound disrepectful by using the word "Indian" and in fact, there are those who do have valid, strong objections to the word. I prefer the generic term 'native peoples'. In truth, speaking for self only, whatever slang is used doesn't matter much, because I am Puyallup, and nothing else.
I think this misunderstanding, though, points out exactly the issues that you were invited here to learn about. There is concern that Pagan folks are being misled by those who pretend a high degree of knowledge or expertise of traditional native spiritual practices. It creates a dangerous situation for the pagan as they are being taught at best a lie and at worse physica and spiritual damage. "Traditional' native spiritual practices are defined by culture; simply meaning that I as a Puyallup follow a spiritual/cultural path different than a Lakota, a Haida, a Crow or any of the over 500 nations. Spiritual is part of the cultural and cultural is part of the spiritual.
Words have power..as we've already seen in this discussion. Please feel free to ask questions, but please hear the words spoken in response without making judgements based on incomplete information. Thank you.
