I intentionally withhold my biography, I will give you that. That choice is mine. I do not think it is a good practice to judge a person's words, ideas, or information based on their claims, DNA, wealth, title or education. I find it hard not to do, but have been deceived too many times to allow myself to be conned any longer. Phrases like "Officials say", "Research proves," "Doctor so and so says," "I make this much an hour", etc. are sneaky methods to infiltrate our thought process. I do value background but do not choose to use it as a method to support my arguments. You are more than welcome to, I enjoy it. I just do not think it is right to disregard someone due to their background. I will read and listen to everyone, any educational background, philosophy, religion, or life experiences. I judge people's arguments based on the merits of their words, not by any other attributes.
Concerning Native Americans. We are given a picture of them in school that is painted in generalities. I would guess that you were given one that generally portrayed them in a more savage light. Today's children are given the generality of a Noble Indian and one that preaches Environmental Activism and Nature Love. Personally, I believe that there was no North American Indian philosophy, that there were many tribes, all different, and differences among the individuals in those tribes. While they may have shared a similar metaphysics to some degree, they did not hold a common doctrine such as the Amish do. We may be taught the pipe ceremony and be given the words of Chief Seattle as an example of what the Natives thought, but these are not representative of the common indian in my opinion. The only common thread among Native Americans that I know of is Tobacco. In fact, it was mainly pipe smoking. While there were pipe ceremonies, I believe the sense of sacredness pervaded every aspect of the lives of at least some if not the majority of Native Americans. Life was not as easy for them as it is for us, recognizing the blessings we receive is more common when life is difficult. I also believe that they held tobacco to be a sacred herb in it's own right, the idea of a Nicorette chewing gum ceremony is silly. Extracting the virtues of the tobacco plant to reap the benefits of Nicotine is not something they would generally accept.
