It is touching that the Right has managed to transform the holiday season into another hate fest. But, let me say this -- when the occasion arises, I tend to say "happy holidays." Not because I'm worried about offending people. Not because I'm trying to be overly inclusive to people of all faiths. It's because it really feels fucking stupid saying "Merry Christmas" on December 1 when Christmas is over 3 weeks away.
The "holiday season" is that period from Thanksgiving until New Years. If we count Thanksgiving, which we should given the ever-lengthening advertising campaign which seems to define the season, that includes 3 federal holidays, one of which falls on December 25. Now, some people may like wishing others a "Merry Christmas" over a 40 or so day period which encompasses the "holiday season," and good for them, but I personally like wishing people a "Merry Christmas" on or about the actual day. I even think it may be what the baby Jesus would want, though I'll have to check with Pope O'Reilly I.
