"manicman,"
Raven Kaldera is a fraud and so is this Tashlin guy. They are both ripping off, mangling and misrepresenting Indigenous ways. They are just more clever about their marketing than many of the other frauds.
They both base their practices on Harner's work, which is a misrepresentation of Plains traditions. They dress it up with things taken salad-bar-like from other cultures as well, as do all of the pseudo-ethnic shameons, but it's Harner at its core. (No pun intended.) There are plenty of quotes in both the Kaldera thread and the Harner threads that establish this. But once again, you care more about how these exploiters make you feel than the harm they do. Both these guys harm the cultures they steal from as well as the people who come to them. Read the threads.
As people have told you before, "manicman," as a white guy, and one who has shown himself to lack empathy for the victims of these frauds, you are in no position to declare whether someone is "the man" or "the real deal."
