The billboard in question, sponsored by the Freedom From Religion Foundation, reads: “Enjoy Life Now. There Is No Afterlife.” American Atheists president David Silverman unequivocally praised the message as “the truth” and one that encourages people to pass a “good legacy” on to their children. “Take care of your fellow man because God is not going to do it,” he added.

In return, Catholic League president Bill Donohue took the opportunity to stab at Silverman’s intelligence, suggesting that only “intelligent” people understand that there is a “higher being.” When the atheist called him out for the insult, Donohue retorted: “I’m not sure how much intelligence there is to insult.”
