Pharyngula: Have a jolly godless Christmas, all!: "Richard Dawkins celebrates Christmas. Greg Laden celebrates Christmas. PZ Myers celebrates Christmas. We aren't celebrating the Christian faith (we actually deplore that), but we do like parties and music and good food and a seasonal tradition and having fun with our kids.
I have no problem saying 'Merry Christmas!' to people, or putting on a red santa hat, or seeing houses draped with Christmas lights. I'm joining in. It's my way of subverting the tradition — it's also a secular holiday, you know, and I aim to appropriate it. I'm following another tradition there, since Christians initially stole the pagan midwinter festival for themselves, so I'm planning to take over Christmas as an atheist celebration."
Great idea, I guess I've been doing that all along! Merry Christmas Everyone! And Happy Newton's Birthday!
