An atheist group called American Atheists is using a fake "Dear Santa" letter in a billboard campaign in several Southern states, urging people to skip church this Christmas and stop listening to "fairy tales."

The billboard - which is positioned near several churches - features a little girl's letter to St. Nick that reads "Dear Santa, all I want for Christmas is to skip church! I'm too old for fairy tales."

The group claims the billboard targets closet atheists who are pressured to observe religious traditions.

Kennedy said on "Outnumbered" today that atheists should just come out and admit that atheism is a religion.

"If you are taking out a billboard that deals with God - whether it is the negation of God or the existence of God - the fact that it is about God ... that makes you a religion," she said.

"Why would you mock a little child during Christmas? Not the smartest marketing strategy," she said.
