Union Tribune columnist Logan Jenkins wrote a good piece on the parade name change. link. He brings up an excellent point, the stores don't care what you call it:
In this mercantile context, Christmas could not be more inclusive. The more shopping the merrier. (And we don't care if you call them Hanukkah presents!)
On this plane, Christmas is a money-driven revelry that, long ago, exchanged the soulful Jesus, a spiritual prophet whose world view was something of a downer in the marketplace, for the materialistic Santa Claus, the emcee of plenty.
Jenkins also makes this wise obsevation: Dalager is right – and wrong.
