*founded one part of America

New England isn't the whole USA, that'd be like saying all of Germany is Swabia. Pennsylvania was founded by Quakers, not Puritans, while Virginia and the other Southern colonies were largely Anglican and had nothing to do with Puritanism. Then of course we have Maryland, which was founded by Catholics, the arch-nemesis of Puritans.

Boston likes to claim a sort of monopoly on American Independence War history, but lets not buy into their cheeky attempts to portray the whole country as them alone.
