The movie "The 40-Year-Old Virgin" has been brought up countless times when discussing the life and death and murders of Elliot Rodger, who killed seven people including himself last week in Santa Barbara, Calif. Is it any wonder the worst thing in the world for Rodgers was that he was not having sex? "Sex has become a sort of replacement god, an idol of our Internet age," says Dr. Aaron Kheriaty, the associate clinical professor of psychiatry at the University of California Irvine School of Medicine, observes.In the writings he left behind, Rodger pointed to his parents' divorce and his first viewing of porn as perversely formative.
