On the other hand, one of the reasons the Pilgrims had such a long period of peace with the Indians was the arrival of various Eur/Asian/African (Old World) diseases that wiped them out ~ mostly in 1646/47/48.
I'd suggest that by 1676 (and the Pequot, et al, uprising) there'd been enough gene flow from the arriving European population to the existing Indian population to have created a new type of warrior ~ one with inherited partial immunity to the Old World diseases.
Gene flow. Never heard it called that before.
People who came later however, were not so understanding and also tribes in other areas were more warlike.
The combination of settlers who were less tolerant plus the more warlike tribes, such as the mohawk, and the mother of all eastern tribes, the Deleware, and all the other eastern and north eastern tribes, and the fact that the British and the French used various tribes in their wars against each other was not condusive to the survival of the native Indians.
Down through history more advanced civilizations have absorbed or wiped out less advanced civilizations. It isn't the ideal situation but it is the way it was. Crying and moaning about it now will not change things.
Making the pilgrims, the least offensive of the people who came to these shores, is ridiculous and this tribe in SF that did this is showing their prejudice and lack of understanding of the way things really happened.
