The first Christmas was shared with foreign religious scholars, animals and even an unwed couple. The entire holiday was a hope for all people. The Christian Church cannot copyright that message and limit it to ourselves. The message of Christmas has nothing to do with capitalism, American pride, or Christian exclusivism for that matter. The message of Christmas is heard in the angels’ song, “Peace on earth, Good will to all!”*  Any who try to restrict that message to their own group are the true assassins of Christmas.
(*I am aware that the full scriptural quote is “Peace on earth, good will to all with whom God is pleased.” I am quoting the hymn here. No need to send comments that I am twisting scripture and that God means your own group and not mine. Rest your weary fingers, my friend, and hear what the angels are singing to us all.)
