Leander, I too was a MS ,literature servant for many years.I turned in my "resignation" a while back. I used the cognitive dissonance approach. The lack of references,the anonymous quotes,quoting dead people,works no longer in circulation as prohibiting me from "making sure of all things" causing me distress,losing sleep etc....
I had one meeting with them afterwards.They threw the "do you believe its Jehovahs' organization" question at me. I said I did(past tense) but my conscious would not allow me to teach anymore. That was 2 years ago and they have left me alone. One word to the wise,DO NOT openly criticize if you want to do the 'fade away'
