When I pressed those few people to whom I could open up about the org's corruption (less than 1% of Witnesses I knew), I found two basic reactions. 1. They agreed and eventually left themselves or were DFed for apostasy. 2. They admitted there were problems or even were aware to some degree of the real corruption that those who are enlightened can see, but at a certain point they cut me off in one way or another. I've come to conclude since that in the latter case, such behavior on their part was necessary for them because of the threat posed by the cognitive dissonance that facing the truth posed to them. Their minds just were not strong enough to fully face the facts.
At the end of Ray Franz's CofC book, he relates the case of some sister who learned of the org's corruption, became lost, didn't know what to do, and so wrote him. Although Franz never came out and said this, the implication seems to be that it may have been better in the case of this woman to have never learned the truth (that is, TTATT, The Truth About "The Truth," or the facts of the org's corruption), for he said he couldn't really offer her anything other than "just go ahead and live your life as best you can." In other words, water down the Christian life to the social gospel, like so many of the liberal churches have done. For this woman that did not seem to meet her personal needs, the point of Ray's relating the story.
If you want to have personal discussions with those still in about the org's corruption, it is good to always try and figure out the mental strength of each person to whom you want to open up about the matter. Few can really handle it themselves, and you may unintentionally frighten them, and THAT can come back to harm YOU.
My two cents' worth of advice.
