I think that if you're going to celebrate the birth of the person labeled by Christians as "The Savior" you should sing about that, not about stoplights blinking red and green or a red-nosed reindeer. If you are going to celebrate the rebirth of the Sun, your music and songs should celebrate that. If you wish to celebrate the Feast of Lights, great!, and sing about that.

Or do what I do, and enjoy all of these celebratory songs.

But I'm sick unto death of people singing "Jingle Bells" as a Christmas carol and similar songs.
