The nation does not celebrate Christmas. We celebrate commerce. It has become the god of the US. We have come full circle. The birth of The Christ was celebrated on a pagan holiday. Now the day of that celebration is used to celebrate a pagan god of gold, commerce.
Reminds me of an old cartoon from fifty five years ago. A man is on his knees in front of a Christmas decoration. he says to his wife...”To YOU they are THREE WISE MEN! To Me they are the PATRON SAINTS OF ADVERTISING!”
