In Boston, for instance, the Puritan fathers banned Catholic priests....
Cotton Mather, the famed Puritan cleric, led the war cries against New England's Abenaki "savages" who had learned their prayers from the French Jesuits. The colony of Georgia was established in 1732 as a buffer between the Protestant English colonies and the Spanish missions of Florida; its original charter banned Catholics. The bitter rivalry between Catholic France and Protestant England carried on for most of a century, giving rise to anti-Catholic laws, while a mistrust of Canada's French Catholics helped fire many patriots' passion for independence. As late as 1844, Philadelphia's anti-Catholic "Bible Riots" took the lives of more than a dozen people.
The list goes on. Our history is littered with bleak tableaus that show what happens when righteous certitude is mixed with fearful ignorance. Which is why this Thanksgiving, as we express gratitude for America's bounty and promise, we would do well to reflect on all our histories, including a forgotten French one that began on Florida's shores so many years ago.
