I'm just not sure about this authentic personaity idea Lisa. I know the theory but after I've been out 27 years I see no sign of authentic personalities in my siblings. It's true I only see them at funerals but I'm not sure the authentic personality is suppressed by the cult personality. I think each small decision, shun this person, hate that gay person, lie about who will die at Armageddon, changes our personality gradually until we actually become a different person.
Otherwise how do people do evil things? Violent crime? Wartime atrocities? We have to fight to stop ourselves becoming callous, getting compassion fatigue, becoming cynical, being paranoid and xenophobic. So if you don't fight negative stuff don't you actually change your personality over time? Doesn't that happen to JWs?
