It's not even the religious stuff that I can't stand - I don't believe in that part of it either, but if there are people out there who want to believe that a baby was born to a virgin in a barn and didn't manage to pick up even one bacterial infection in the process, they can knock themselves out.
It's more the commercial bullshit (most of which centers around ridiculous Pagan rituals and mythology and has nothing to do with Christianity) that really grinds my gears, to borrow a phrase from my spiritual leader, Peter Griffin. I'd rather celebrate Thanksgiving two months in a row than have to listen to generally terrible Christmas carols while surrounded by glittering Christmas decorations made out of material even a Russian woman wouldn't wear.
And of course, there are the gifts, which tend to fall into three categories:
1) Generic/pointless - Oh wow, thanks for this gift card. So not only did I have to brave holiday shopping crowds in some horrible department store to fulfill my obligation to purchase something I thought you might like, but now I have to go back to said awful department store to get myself something because as it turns out, you don't even know me that well.
2) Crap I didn't want in the first place - Shit, how did you know I was dying to own the latest Enrique Iglesias album? That is some mighty fine detective work considering I hate that song by him that they won't stop playing on the radio, and I haven't actually purchased music in over a decade. Way to go, Nancy Drew.
3) An incredibly cool/thoughtful gift - This happens like less than 1% of the time, so let's not even spend time discussing.
In the end, the best gift I get each year at this time is a solid amount of money from my mother, who knows that if we are going to honor silly traditions, we may as well be practical about it. Shame I'll probably have to spend that money on presents for you lot.
