I see two main problem with these sorts of holy wars over Christmas: people's ignorance about the historical holidays, and the Christian right in the US.

There have always been three sorts of Europeans/European Americans celebrating: Christians (who celebrate the birth of Christ), quasi or lapsed Christians (who aren't much for the religious aspects of the Christian holiday but go to church/mass on the day), and secularists, pagans, and people of other religions who celebrate the secular/cultural Santa/St Nick/gift bringer aspects of a variety of European cultures.

Christmas/mid-winter celebrations have always had two tracks: one religious, one cultural. In some countries where pagan traditions remained strong into the 20th century and the conversions to Christianity didn't run so very deep, days or eves other than Dec 24/25 were, until globalized capitalist Christmas took over the world, still the major celebrations in those countries. That has begun to wane all across Europe now, where the Anglo American capitalist conversion to corporate style Christmas has begun to stamp out local cultures' holiday traditions.

Conservative Christians have always been niggardly about the celebration of Christmas, and believe secularists/pagans/non-Christians shouldn't be able to "steal" or "water down" or "destroy" Christmas as the dominant holiday of the US holiday calendar. Unfortunately, those conservative Christians also control all three branches of the US government, so we are damned if we do, damned if we don't. These people remind me of those intolerant relatives of mine who refuse to change the Christmas dinner menu after 35 years of no one eating the oyster stew.

Fuck 'em all, I sez. Do whatever you want.

Celebrate Las Posadas. La Befana. St. Nicholas. St. Lucia. Nochebuenas. New Years. Boxing Day. Women's Christmas. Joladagatal (w/13 Santas). Celebrate Advent, Epiphany, the solstice, the turning of the year, or whatever your culture (of origin, or adopted, or adapted) compells you to celebrate.

And ignore the dumbass Christian right begrudgers who insist upon dictating to the rest of us how we should live our lives, from the bedroom, to the boardroom, to the halls of government, to the holiday festivities.
