Yeah, one of the historical myths that schoolkids were taught for a long time, especially in lower grades (and probably still are in some schools), is that the Puritans and Pilgrims came here for "freedom of religion." They actually came here for the freedom to practice their religion with no outside interference, and they were anything but tolerant of other religious beliefs, even within Christianity. They established a theocracy in the New England colonies they controlled. Roger Williams, an advocate of the separation of church and state, was convicted by a Puritan court of practicing sedition and heresy for spreading "diverse, new, and dangerous opinions" and was more or less driven from the colony. The whole cute little Thanksgiving story of the local Native Americans, the Wampanoags, and Puritans having a Thanksgiving feast together also looks a lot less cute when you learn that the Puritans basically exterminated most of the tribe in King Phillip's War 50 years later and enslaved many of the surviving women and children and sold surviving male members of the tribe into slavery in the Caribbean.
