Prometheus Books published Parenti's 2010 book, God and His Demons. Writing for the San Francisco Chronicle, Don Lattin said: "God and his Demons is a depressing, mean-spirited book. Much of it is a recounting of the usual suspects we find in the new wave of atheist chic nonfiction - targets like Islamist extremists, TV Preachers, child-molesting Catholic Priests, Christian-right political operatives, creationists, cult Leaders and, for historical context, a reminder that the Crusades and the Inquisition were no picnic either, along with a tired recounting of all those troublesome passages in the Hebrew Bible and the anti-Semitism in much New Testament translation." Calling it an "angry volume" that "makes no clear argument", Publishers Weekly said: "His condescending tirade is directed not so much at religion as at human beings whom—one gets the impression—he can barely suffer."
