The war within the war on Christmas

Every year we get crusaders trying to force people to say "Merry Christmas" instead of "Happy Holidays." You've heard it before. But having store employees say that it seems they are reinforcing the idea that Christmas is a secular, capitalist holiday, not a religious one. So why do it? Perhaps because by tying a religious tagline onto an American holiday they are pushing a tiny facet of the idea that America is a Christian nation and should be following Christian laws.
