He calls this the turning point in his life where he decided never to lie about his atheism again because he had gotten up on stage and told all the people he knew that he believed in God.

[14] An atheist awareness billboard campaign launched in December 2010 sparked controversy and increased media exposure for the organization.

[15] As a result of this campaign, Silverman appeared on a number of television shows since late 2010, most notably, The O'Reilly Factor on January 4, 2011.

It was under Silverman's direction that the American Atheists group sought to block the preservation of a cross-beam section of the World Trade Center skeleton that resembled a cross.

It has been blessed by so-called holy men and presented as a reminder that their God, who couldn't be bothered to stop the... terrorists or prevent 3,000 people from being killed in his name, cared only enough to bestow upon us some rubble that resembles a cross..."[17] On April 13, 2018, Silverman was terminated as president of American Atheists over complaints of financial and sexual misconduct.

[19] The day after his termination, BuzzFeed News published an article detailing allegations of unwanted sexual contact by two women, subsequently denied by Silverman.

[20][21][22] The new president of American Atheists, Nick Fish, specified that Silverman's termination was not over sexual allegations, but as a result of a "loss of confidence" stemming from violations of internal policies on staff management, conflicts of interest, and their general code of conduct.

On March 24, 2012, the Reason Rally took place at the National Mall in Washington, D.C., and was the largest atheist gathering in world history.

[26] Silverman went on Fox News's Hannity to discuss Christmas-themed billboards that American Atheists put up in Times Square, New York City.
