It’s the time of year when spoilsports come out in full force. You know who I mean—the kind of people who insist that people say “Happy Holidays” instead of “Merry Christmas,” or who go around suing city halls that dare to have a Nativity scene on public property. But this year, the Christmas cranks have actually launched an ad campaign to convince us that God doesn’t exist.

The Humanist Association is placing posters on buses in Washington, D.C., featuring a skinny Santa in dreadlocks and the words, “Why believe in a god? Just be good for goodness’ sake.”

Fred Edwords, communications director of the Humanist Association, says that partly they’re trying to cheer up agnostics and atheists, who tend to get lonely this time of year when most of their neighbors are celebrating holy days. Pity. But he says they’re also “trying to plant a seed of rational thought and critical thinking and questioning in people’s minds.”

They never give up, do they? Richard Dawkins, Sam Harris, Christopher Hitchens, and now the Humanists—all spreading and making money trying to convince us that God doesn’t exist and that His followers are a bunch of irrational dopes.
