Fact is humans are in general a violent species, white, black, gray, red, yellow, whatever. We have been killing each other forever and we love it and will continue to do it. What I object to is your notion that natives were somehow immune from this. They committed as many atrocities against each other and white settlers as they were capable of. In the end they are simply one group conquered by another. Once conquered they were given reservations, welfare checks, and health care. If it were the "genocide" you claim it to be then the killing would have continued until there were no more.
