We atheists love the holiday season! It’s the time of year to scowl at anyone wishing us holiday greetings of any kind, be it a Merry Christmas, Happy Hanukkah, or Good Kwanzaa. Even calling the winter celebration Yule or Saturnalia gives us all a smug sense of superiority knowing that we are not yoked to superstition. Whenever we hear the claim "Jesus is the reason for the season," we can counter with the smarmy "Really, I thought it was Mithras," or the coldly scientific "Actually, its the tilt of the Earth." Everyone knows this is the time of year when atheists get out the war paint and roam the streets in gangs knocking down Salvation Army bell ringers and pissing in nativity crèches. Oh, the holiday joy!
Congress voted in 1870 to make Christmas Day a national holiday, thus making in a secular American holiday. Since, as we all know, "congress shall make no law respecting an establishment of religion," (we do all know that, right?) the very act of voting to make it an official holiday stripped Christmas of any religious connotations. Do not be alarmed; there are any number of winter festival traditions in which you can freely participate. As for me, I'm just glad the days are getting longer (up here in the northern hemisphere, anyway,) and I expect to enjoy some family time and some good food and drink.
It makes no difference to me how you choose to celebrate, just please don't insist that your way is the only way or that the season is reserved for those that share your faith.
