Although I'm not a Christian, I've never regarded a heartfelt utterance of "Merry Christmas" as a disparagement of my beliefs. But that was before that salutation was turned into this season's battle cry by the right. James Wolcott offers his observations on that controversy here. For a more ironic take on the subject, try Michael Bérubé. In the meantime, all members of the reality-based community might consider making the winter solstice their big festival, since it marks an actual physical event. But whatever you celebrate, my best wishes for happy holidays!
