Ya'll are really harping on the fact that he brought up his ancestry. You must be reading his posts in the voice of a cartoonish villain. Extend just a smidge of good will, and it becomes clear that he wasn't going on about the amazing super powers he's given by the native blood coursing through his veins. He was talking about the source/inspiration for his knowledge, and was expressing the respect he had for the knowledge of the past.
He was civil and respectful and I see no indication that he was coming here to stir up trouble.
If, hypothetically, someone *did* come up with an amazing new heat treating method, I would not expect them to start making the best bows ever. As you all know, an enormous amount of skill and knowledge goes in to making a fast bow. Much more than any heat treatment. To suggest that if someone with a better heat treating method would be automatically making amazing bows is to shit on the knowledge of people like Marc St. Louis. I wouldn't expect to start seeing the best bows ever until this new method got in to the hands of someone like Marc.
Again, I'm super skeptical too. If it's a scam, I will definitely be among the annoyed. He makes big claims. But he's also been good and civil and unfairly jumped on. I don't know enough about his method to say it's bs, and neither do you. Express your skepticism and move on. I don't understand why this has become a witch hunt.
