Bob Ritter, an attorney for the American Humanist Assn., argued that when a celebrant marries a couple, he is acting as an agent of the state. Therefore, it’s unconstitutional to block someone from holding that position based on his religion — or lack of it, he says.

“Many atheists and agnostics have . . . deeply held beliefs,” Ritter wrote in a letter to Parraguirre. “Are not their beliefs entitled to the same respect?” Nevada law, he continued, implies that “the religious are more trustworthy than the nonreligious. This is a bigoted assumption.”
