Even women who were captured by the Native Americans and forced to marry into the tribe, once they were in, found they had a higher status and more freedom than they did amongst their own people.
I'm not sure where you're getting this information.
One of the tribes I'm descended from, some 6-7 or so generations back, is the Wampanoag ( subset of the Massachusett ), and they were known for being friendly, but keeping their distance from white settlers, for the most part...although they did render aid to Plymouth Colony in their time of need ( from that and other associated events we Americans get the modern Thanksgiving story.
)
Other tribes in the area, depending on region, ran the spectrum from passive to hostile.
The Mohicans ( Mohegons ) were basically middle-of-the-road, while the Narragansetts were friendly, I believe.
The further west one traveled, the more chance there was of running into the Hurons, the Ticonderoga and other members of the Iroquois Confederacy; some of whom were very jealous of their territory.
Each tribe had rules regarding outsiders...some were used as slaves, some were killed outright, and some were adopted as equals or allowed to live near them in their own, separate settlements.
These are facts of history. Calvinism is and has always been an oppressive religion.
No wonder John Piper has no pity on people in tragedy.
All kinds of things are done in the name of religion, usually by people who are caught up in moments of fear, zeal and associated with all kinds of mixtures of true and false doctrines.
As for John Piper, I understand that he is a very compassionate man...he just sees the facts of Scripture and acknowledges that salvation is
God's territory, and not man's.
The pilgrims and large numbers of European settlers believed the new world was their promised land, the heathens that inhabited were like the Cannanites.
I agree, to an extent, but why paint the whole thing with such a wide brush?
Many of the people who came to the New World were looking for freedom from religious persecution, much of which they were experiencing at the hands of the
Roman Catholic Church...which, again, taught and
still teaches a form of "Semi-Pelagianism" called "Molinism" ( think: modern, 5-point Wesleyan "Arminianism" )....not "Calvinism".
IMO, you're also confusing the Puritans with the "Pilgrims" in at least one place that I can see...they were
two entirely separate groups with separate charters.
The Massachusetts Bay Colony was chartered by Puritan separatists from England 8 years after Plymouth Colony ( chartered by people who left England, lived in Holland and then came back to England and were granted a charter before going on to the New World ) was settled...
If you check their beliefs and circumstances, they were fairly different, and their treatment of the native peoples was, again, different
Plymouth Colony were generally good neighbors to the Wampanoags, while the other Massachusett tribes around Boston and the Puritans suffered worse treatment, from my research.
Finally, the Salem Witch Trials were perpetrated by misguided, zealous and very paranoid Puritans who forgot God's commandment...
love thy neighbor as thyself.
Some of the atrocities you speak of were committed by religious zealots who, yes, claimed to believe the doctrines of grace ( from what I understand ), and some were committed by those from the "other side of the fence".
With respect, I think you should do a little more reading, good sir.
