Well Swampy I am half Cherokee and I too have never heard the term "First Nation", and am not sure whom gets to decide is "First Nation", and whom is not, and why it would matter. I have no idea whom was here first, and have long since given up on "hyphenated Americans". I am an American that happens to be Cherokee, and although I am proud of my Cherokee ancestry, and enjoy reading and learning about it, it is not what runs me.
If one looks back on American Indian culture one quickly learns that the American Indian was an individual from the beginning of his upbringing. If a group wanted to go to battle with another group, and an individual didn't agree, he simply did not go, and was not thought lessor of.
So the lesson here is, you quoted a sentence from an entire thought, from someone other than whom you thought said it, and someone else was more familiar with the actual person that said it, and shared it with all of us. Your point wasn't lost, it was expanded, and rather well with the ENTIRE quote.
My ancestors too were cruelly treated and marched from Georgia, and North and South Carolina, all the way to Oklahoma on the "Trail of Tears". They lost family, and friends, and were not even allowed the time to bury them. Children whom could not keep up were abandoned at gun point and left to wander and die in the woods.
Tecumseh, said it well, and his entire quote added to yours made your point more clearly.
