[I previously quoted a different portion of this passage; the first sentence quoted here seemed important to both excerpts, so it may sound familiar.]
"Personality theory and social psychology research suggest that when we encounter someone whose arguments for censorship are dogmatic and simplistic, we are probably dealing with an authoritarian personality who is reacting to something he/she fears. [...] The theory of cognitive dissonance tells us that authoritarian personalities will defend their choices most strongly in ambiguous situations, since they want to erase the inner conflict created by the recognition of two positive but conflicting ideals (such as freedom of speech vs. the preservation of family morals). [...] Reasoning, intellectualizing, moralizing, or standing behind regulations or procedures will fail to appease the authoritarian personality. Tactics which show more success include active listening, surrounding yourself with power an acting with confidence, offering the authoritarian some form of power, and avoiding situations which prompt the authoritarian to defend him/herself." -- from the abstract for "How the Mind of a Censor Works: The Psychology of Censorship", by Dr. Sara Fine, School Library Journal 42 no. 1 (January, 1996): 23-27. [I was not able to find the complete paper online, only the abstract. I'll try to remember to see whether I can find it in a public library the next time I find myself near one.]
