re: all the fuss about Jingle Bells’ username. For the record, though I would not use that name myself, there is NOTHING non-Jewish about it. The song Jingle Bells is a WINTER, not x-mas song, though clearly it is sung at this time of year.
If you check out the lyrics of the song, there is no reference to anything of the non-Jewish holiday, to the fat man in the red suit, or anything offensive. It is a seasonal song. People sometimes get offended for things that they perceive, before knowing if what they perceive is the fact. Hevei dan….etc.
