Research shows that as soon as europeans landed on the this continent, european disease decimated most tribes. Thier is evidence after the pilgrims that blankets with small pox were given to Indians on purpose. I am not saying that they didn't hunt down natives of this country like dogs. So much evil.
That's way it's so important to pass on history, not just horrible things that were done.
