"Altough my trump card is that I have not shared my thoughts with anyone including my wife, and my father who has been an elder for many years says a comittee can only be formed if i begin spreading my ideas."
After reading countless testimonies and seeing how several different congregations work myself, I can confidently say.....it all depends on where you live and who your elders are. Some have said they've been asked "the question" (do you believe that the FDS is directed by Jehovah). And when they answered "no" that was all that was needed to DF them. Others, such as my father, verbally and abusively tore into the elders and the CO about the crap that they spread....and yet never got DFd.
So....it depends on their agenda. Do the local elders like you? If they do....I honestly think that unless you start spreading your doubts around....they may not DF you if you are honest with them. If they don't like you....they may be looking for ANYTHING at all they can dig up against you.
The safest bet is to say nothing
