Andyon: You are not credible. Three months touring the US?
The island where you live could fit, tip to toe, in the state of California. California is not even the longest of the coterminous states.
It is 3,360 miles from Seattle, Washington, to Miami, Florida. And on this route you could have met Snowamish, Cheyene, Dakota, Souix, Navajo, Hopi, Acoma, Laguna, Seminoe people -- to name just a very few of the tribes.
And, SHOCK, these Native Americans would be living and working just like ordinary people! Attorneys, government employees, and small businessmen and women.
On the way, you would have driven on the "Indian Nation Turnpike" in Oklahoma, a state which is wider than the widest part of the island on which you live. And Oklahoma is not even the "widest" of the coterminous states.
Did you plot a tour in the United States to AVOID us Native Americans? Did you ASK anyone about Native Americans? Could you even IDENTIFY a Native American if one were standing in front of you? Do you think they ALL LOOK ALIKE?
Your post shows no understanding of the social and political situation in the US.
