Is there such a thing as an inoffensive atheist billboard?

As we all know, billboards with atheist messages seem to arouse indignant responses because of their purported offensiveness. Richard Wade wonders if it is the message itself or simply the fact that the word ‘atheist’ appears in the billboard sponsor’s name that drives believers up the wall.

To test his hypothesis, he suggests a number of billboards. Pretty funny.
