Wars on Christmas
Here’s an informative article about the history of Christian sects in America that declined to celebrate Christmas (and on one occasion, banned it).
Observance of Christmas, or the lack thereof, was one way to differentiate among the Christian sects of Colonial and 19th-century America. Anglicans, Moravians, Dutch Reformed, and Lutherans, to name just a few, did; Quakers, Puritans, Separatists, Baptists, and some Presbyterians did not.
On the subject, Andrew Sullivan has a very sane article on the current WAR ON CHRISTMAS, while Christopher Hitchens has a very funny, slightly mad one.
