Magnum,
JWdom attracted some really smart, stable people. I was there; I saw it. I remember the deep, exciting poolside discussions after district convention sessions. The look and feel of JWdom were just so different back then.
I too remember having those deep discussions with two brothers ("fleshly"). One had an IQ of 170. We talked about representative Christology" an Arian, JW type of understanding of Jesus and his role in relation to Jehovah. He ordered a special Bible with annotations in the text.
The closest he came to criticizing the Watchtower was to say that they dumbed things down. Mind you, this was in the 1970s. "Simplification to the point of falsification" was his view of the Watchtower articles.
I wonder if he's still in there.
