That's about it. He's a born-again drunk Yalie-legacy frat boy who got over all the coke, booze, and girls. He's a veritable Augustine, and they fear his example. That business about his being stupid (seizing on his dyslexia, which his dad also has, and his mediocre academic record at Yale, which he loused up with his partying) is pure invention and raw need. They absolutely need him to be as bad as they say he is, for their own egos.
Very well said. And I would add that they need Christianity to be as "bad" as they say it is in order to excuse their life styles.
