The American Humanist Association has ads out in D.C. that say "Why believe in a god? Just be good for goodness' sake."
Here's more information from the Pew Forum on this:
I find it fascinating that these people supposedly don't believe in God and yet they form a group to "not believe in God" together.
Hmmm...I also find it humorous that atheists keeping saying they don't believe in God and yet...keep bringing Him up!
A person who really, truly does not at all believe in God does not care to identify himself by his "non-belief."
I don't exactly know how to judge this absurdity on behalf of the AHA. Should I be outraged because they are offensive and intellectually dishonest? Or should I be delighted that such an extreme measure shows how much they really want to believe in Him?
