Welcome, Englishman. I also had a run-in with Vincent LaDuke ("Sun Bear") and his crowd back in 1984. Some friends of mine with alleged distant NDN heritage brought me to one of his "Bear Tribe" gatherings. From that one, weird weekend, I saw some people who I knew were white start trying to pass as NDN. Some bought pipes in the marketplace, and had LaDuke "awaken" them for them by simply holding them briefly. Then they returned to the Neopagan community, proclaiming that they were now "pipe carriers", given the right by LaDuke. One white Wiccan even proclaimed herself a Medicine Woman, came up with a whole new backstory for herself, and started a women's drum group. She fooled lots of people in another country. Lots of Neopagans attended that same gathering, and I watched LaDuke and co's newage versions of smudging and fake ceremonies be carried back to Neopagan gatherings where they became an unquestioned part of many people's modern "traditions". I had thought the Neopagan community would be better, but eventually I found the same thing you did: massive egos, greed, alienated people with personality disorders proclaiming themselves spiritual leaders, and it's still going on. From what I occasionally see on the Internet, I think it's gotten far worse since I've disengaged from those people.
