I'm a strange cat in that my holiday wishes extend to those of every faith or lack thereof. I also strangely enough was never offended by someone saying Merry Christmas to me. It's generally either a pleasantry or a well-wish.
So, to all... may you be geltfree this holiday season, may your dreidl land approriately, and when you are in a time of sparcity... may you find light, comfort, and community.
(and yah, I made a bad assumption)
