No, the first ones were likely the Vikings, who were Pagan. If not the Irish, FLEEING the Vikings who were ALSO Pagan at the time.<quoted text>
They weren't atheists who came ashore in New England.
LATER, there were those fleeing England, the "happy-go-lucky" Puritans who outlawed the celebration of Christmas. Is that REALLY who you want to pretend set the whole tone for the country?
And let us not forget, that the first REAL Americans, were the Native Americans, who were most definitely NOT Christians, you arrogant thing.
