I have read of some who are loathe to celebrate #Thanksgiving, because of later injustices done to the native Americans. The issue is succinctly summed up by Michael Medved for PragerU:

What’s the Truth about the First Thanksgiving?

An accusation I have seen, coincidentally all on secular and ideologically radical biased media outlets, is that the natives who shared in the first Thanksgiving with the Pilgrims were afterwards slaughtered by them.

What could be the motive for spreading so egregious a lie? Everywhere we look, we see a flood of words with, it seems, a dual focus of tearing down both our biblical foundations and our patriotic spirit in American history and institutions.

And the serpent cast out of his mouth water as a flood after the woman, that he might cause her to be carried away of the flood. Rev 12:15

This symbolic language pictures a flood from the enemy’s mouth; for it is words that come from mouths. And this notation occurs in the very chapter of Revelation dealing with the arrival of the children of God in America!

The fact is the peace treaty between the natives and the Pilgrims of Plymouth was unbroken for over fifty years, or in other words, for the entire duration of that first generation of Pilgrim Fathers and Mothers.
