From Hullabo:

Wal-Mart said Thursday that a customer service employee named Kirby had written an inappropriate e-mail to a woman who complained that the retailer had replaced a "Merry Christmas" greeting with "happy holidays." The company, based in Bentonville, Ark., also said Kirby no longer worked for Wal-Mart.

Kirby wrote that Christmas resulted from traditions such as Siberian shamanism and Visigoth calendars.

"Santa is also borrowed from the [Caucasus], mistletoe from the Celts, yule log from the Goths, the time from the Visigoth and the tree from the worship of Baal. It is a wide wide world," Kirby wrote.
