I posted similar thoughts a while back: http://www.jehovahs-witness.com/topic/474120002/why-trying-reason-jw-out-cult-lost-cause-what-solution-might
While I definitely believe there's a place for reason and facts and all that jazz in waking up a JW, I think it takes a secondary role. I woke up purely because I determined the doctrine to be false and I had been intentionally lied to, but I still had to be in the right emotional place before I could accept that. There had been sufficient evidence to tell me I was in a cult for my entire adult life, but accepting the evidence and seeking out more potentially faith-destroying evidence is something that most will not do until they're emotionally ready to do so.
