From Christianity Today:

For Conservative Christian groups, this year’s hot gift is a weapon for fighting back in the "War on Christmas," be it a button, a bumper sticker or a memo with advice to the troops.

The Mississippi-based American Family Association says it has sold more than 500,000 buttons and 125,000 bumper stickers bearing the slogan "Merry Christmas: It’s Worth Saying."

The Alliance Defense Fund, a Christian legal aid group that boasts a network of some 900 lawyers standing ready to "defend Christmas," says it has moved about 20,000 "Christmas packs." The packs, available for a suggested $29 donation, include a three-page legal memo and two lapel pins.

And Liberty Counsel, a conservative law firm affiliated with the Rev. Jerry Falwell, says it has sold 12,500 legal memos on celebrating Christmas and 8,000 of its own buttons and bumper stickers.
