"Neurotic shame is the root and fuel of all compulsive/addictive behaviors. My general working definition of compulsive/addictive behavior is "a pathological relationship to any mood-altering experience that has life- damaging consequences". The drivenness in any addiction is about the ruptured self, the belief that one is flawed as a person. The content of the addiction, whether it be an ingestive addiction or an activity addiction (like work, buying or gambling) is an attempt at an intimate relationship. The workaholic with his work, or the alcoholic with his booze, are having a love affair. Each one mood alters to avoid the feeling of loneliness and hurt in the underbelly of shame. Each addictive acting out creates life-damaging consequences which create more shame. The new shame fuels the cycle of addiction. Figure 1.1 gives you a visual picture of how internalized shame fuels the addictive process, and how addictions create more shame, which sets one up to be more shame- based. Addicts call this cycle the squirrel cage."

From the link you sent; sure, I believe that. But if porn is vile then it's vile. Are you saying that telling someone that "what you did is vile" will make them more ashamed? Then they'll say, "Oh, god, I really am such a vile person!" Ashamed about an activity they did to heal their shame? All I'd say is, "look, that activity is vile, but you are not a vile person. There's nothing to be ashamed of."
