I know a lot of people are of the opinion that saying "Happy Holidays" is offensive to Christians or something, but really, it's not like any one faith has a monopoly on the midwinter celebrations. I think more religions have a holy day at this time of year than any other. I'm not wishing people a Merry Secular X-Holiday here, it's a shout-out to adherents of any and all holy days. Celebrate the death of the old year, the Winter Solstice, the magic lantern, whatever your heart desires!
