A Satirical Look of the Evolution of Christmas

In the Victorian era parlor games were the fashion, conducted of course in a room named the "parlor" that could be found in middle-class and wealthy homes as a place to entertain guests.
One of the games was where the guests and hosts would sit in chairs in a circle and one person made up a phrase to whisper to the person to the left or right of them and then repeat it until the last person received the phrase who would repeat what was heard out loud. Invariably the phrase was quite different from what the first person passed on and that person spoke the original phrase out loud to compare to the result of passing it on.
The concept of the game was based upon the phenomenon known as gossip. If you live in a county or community such as where I live, you know how gossip works - much like the Victorian parlor game.

On that concept, and the way Christmas has evolved since its conception, we can see the value of the written history versus oral history; but even written history can be changed over a period of time - much like the American Progressives have done with the textbooks used in our educational system.
Using this concept and assuming that human civilization continues on its path of self-destruction, the scenario is that technology in the form of computerization has replaced books and because that technology depends so much on electricity the world suddenly finds itself without those conveniences and is thrust back into a world without technology. With no books to refer to, assuming the Marxists haven't completely written all of them or destroyed them that does not suit their premise of what is and what isn't - history and tales of events is then resorted back to oral history and technically humanity must start over again. The parlor gossip game applies.
Christ's Mass [in Old English - Cristes Maesse] evolved into Christmas (which still had Christ in the word who was the 'reason for the season') and so did the traditions change where Saint Nicholas became Santa Claus and then eventually into a generic holiday where exchanging gifts was the key and even the traditional decorations changed along with what became known as "political correctness". 
Time passes into decades and decades into centuries and anthropologists and archaeologists of the future describe life of human civilization and relays the concept of a human festival called "Christmas" which orally evolved as such ...
"Once upon a time in a place called 'Old London' ruled by Good King Wenceslas. The people of Old London worshipped the great god of 'Santa', a creature with fearsome claws and his wife, Mary.
And every Christmas Eve people of Old London go to war with a country called Turkey. They then eat the Turkey people for Christmas dinner."
