Why do we still celebrate Christmas? The Bible doesn't say when Jesus was born, and the estimate is he was a summer birth. The pagan festival of saturnalia is probably what we owe the tree to, and the eating of geese, gift giving, and decorations we owe to Charles Dickens. Good will to all men hadn't been heard of until the publication of a Christmas carol. To add to this we have a German fairly tale featuring a guy called sinta Klaus. I used to think I hated Christmas because other people's joy reminded me of what my life was missing, but I now think I reject it because it's based on a disjointed and fictional basis. In short it's a lie, and people can detect lies unconsciously. There have even been characters created to discredit those who might question the lie, namely the Grinch and Ebeneezer Scrooge, and the not so witty insult bah humbug.
I think retail superpowers are heavily involved in keeping a needless and wasteful tradition going, and without the gross levels of consumerism and gaudy materialist culture they espouse, we would simply revert to all getting dressed up as women and running to the top of whinberry Naze. Everything else is simply a scam and a lie.
