So why don't you ditch the illusion this holiday season and believe in the One who gives real meaning to the season.
Ask an atheist next time what their atheism does for the starving mother of dying children in Sudan. Ask them what hope they have to offer other than oblivion. See if you can catch the next celebrity atheist on his way to the next round of Champagne and caviar buffets. Then ask yourself, if in a thousand years humanity agrees that selective genocide is the only way to control overpopulation, what the modern atheist could appeal to in order to say those looking to curb the population through genocide are wrong.
Once you've done so, you'll see why the only myth and illusion this holiday season are those who insist their universe of 'is' contains any objective 'oughts'. Then you might decide it's time to find that objective source of meaning. A source the could lead all the way back to a babe in a manger.
