Atheists are spreading their version of holiday cheer with a billboard that's raising more than a few eyebrows in New York City's Times Square.

The group American Atheists' latest display includes images of Santa Claus and Jesus and reads, "Keep the Merry, Dump the Myth."

The group's attacks on Christianity have become routine.

"We chose Times Square because it is a place where people go to shop and be festive, which has nothing to do with religion," American Atheists President David Silverman said.

Silverman also told Fox News, "Most Christians are really atheists who feel trapped in their family's religion. They need not be Christian to enjoy the holiday season."

The Catholic League has battled with American Atheists' campaigns. The Catholic League's spokesman, Bill Donohue, said he believes the group went too far this year.

"This year it's different," Donohue said. "This is vile. When you depict Jesus on the cross with a crown of thorns, this is exploitative. We as Christians never harass, intimidate, or insult atheists. But they can't seem to say, 'We simply disagree with you.' They have to insult us."

The billboard will remain in Times Square until Jan. 10, 2013.
