This is a really interesting article on the Smithsonian site. Turns out some things never really change, especially when it comes to glossing over the truth about religion-fueled hatred.
The much-ballyhooed arrival of the Pilgrims and Puritans in New England in the early 1600s was indeed a response to persecution that these religious dissenters had experienced in England. But the Puritan fathers of the Massachusetts Bay Colony did not countenance tolerance of opposing religious views. Their “city upon a hill” was a theocracy that brooked no dissent, religious or political.
