What I know of it that 5 or 6 native tribes banded together to exterminate the pilgrims, but one tribe, fearing they too would be attacked, sided with the pilgrims and warned them. The violence was against the pilgrims. What the alleged 1619 event has to do with this is completely unexplained.

There is an explanation. Every time you have a bad actor in a group of people progressives like Joy Reid want to blame the whole group.
