Rush Limbaugh explains his "nonconformist" behavior. I'm not sure I'd call it nonconformist. Watch how Rush beams in the beginning when William Shatner flatters him. Shatner asks Limbaugh if healthcare is a right. Limbaugh says no. Limbaugh goes on and on about his hearing loss. He says his drug problem made him a better person.
He really is fascinated with himself, which, in psychological terms, means he's a very insecure person. The sockless fuzzball just wants to be loved.
