For the most part, Christmas is built on consumerism and glossed over with tales of the True Meaning of Christmas, often about how rather than focusing on receiving gifts, one should put more into giving gifts to others. Which, ironically enough, encourages consumerism by giving it a better image. And these True Meaning of Christmas Tales sell very nicely to top it all off.
The Real True Meaning of Christmas, however, is Christianity, often with a dash of smug Evangelism and hatred of non-Christians on the side in the classic American fashion.
