Cappytan,
This is the problem with a cult. There are levels of information control they employ in the WT. Some information is for the public, some for rank and file and some for elders and so on.
This is rank and file information. WT want all JWs to think that critical thinking is a must and that they all do it, but the elders condemn anyone who criticises the WT or GB. So all JWs know you can have critical thinking as long as you agree with the WT and GB always as they are always right.
This doesn't sit well with many and they develop cognitive dissonance, they wake up and leave WT eventually.
I have woken up family members. Our family experience was awful and waking them up to TTATT was easy as they new the wrong that we were experiencing.
