I have to say I read some books about jws that seemed flawed compared to my knowledge of Bethel and WT history. Ray Franz' books hit me as truth though and moved me to contact him when I was yet going to meetings.
This echoes my experience Blondie. I had always been an avid reader - even in my JW heyday - and an awful lot of the so-called "anti-JW literature" was either flawed in its reasoning or so venomous it put me off. "Thirty Years a Watchtower Slave" hit a receptive nerve but came across as overly bitter.
The work by the Canadian ex-JW (Bill?) Penton was one of the first that was even-handed and calm in tone. And Ray Franz's Crisis of Conscience was the very antithesis of what the organization said ex-JWs were like. The respectful tone and evidence-based reasoning were - and are - powerful and very difficult for thinkers to minimize and ignore.
We are all in different places as regards TTATT.
