Atheism is Bad News According to Atheists

The atheist bus poster in Genoa translates: (see picture right):

"The bad news is that God does not exist. The good news is that you do not need him."

Didn't we always know it - atheism is bad news. If my publicity agent came up with that one I think I'd ask for my money back. But then how does atheism come up with a positive sounding one-liner uttered with heart felt conviction and expunged of all cynicism? Anyone...?
