Often your work has my mind spinning long after I read. Still, I am thinking about this guy. In "Christendom", it is most typical (as we see in your work) to cover and hide their "transgressions" /"sins".
I never would have known the things about my ex if I had not found them out on my own. He did not speak of any negatives about himself. He was busy maintaining the false persona. But SA is laying them all out on the table. As you said, he rewrites his story, plays to his audience and names it religion.
But the question is, Is he proud of it? It is so strange to me that he is hanging it all out.
My former, "modern" religious "fellowship" talked about modeling transparency and vulnerability. (But they are in the news now for being a cult. It seems they used the transparency of the "underlings" to hurt, manipulate and control.) Anyway, I guessed that SA's generation would not practice transparency so much and that this idea is a more "modern" thing. I suppose it is as you say, lucrative for him.
