David Silverman is a self-proclaimed "atheist billboard" and "firebrand atheist."  As President of American Atheists, he has been at the point position on many controversial issues (and the occasional lawsuit), and he has just released a new book called, "Fighting God: An Atheist Manifesto for a Religious World."

David spoke with Seth Andrews about the book, the lightning rod of David's particular brand of activism, and the rise of non-belief in America.
