Christians typically every year take up the cause of keeping Christ in Christmas. The American Atheists organization has taking up the cause of keeping Santa in Christmas and dropping Jesus. Here is a sign they put up in Times Square:

Steadfast Lutherans » Keep the Merry…and the Myth.
Similarly, Christians regularly decry the commercialization of Christmas. Ayn Rand, conservatives’ favorite atheist, says commercialization is the best thing about it. From Michael Schmitz:
“The best aspect of Christmas is the aspect usually decried by the mystics: the fact that Christmas has been commercialized. The gift-buying . . . stimulates an enormous outpouring of ingenuity in the creation of products devoted to a single purpose: to give men pleasure. And the street decorations put up by department stores and other institutions—the Christmas trees, the winking lights, the glittering colors—provide the city with a spectacular display, which only ‘commercial greed’ could afford to give us. One would have to be terribly depressed to resist the wonderful gaiety of that spectacle.”
-Ayn Rand, The Objectivist Calendar, December 1976
