This has been an interesting and informative discussion!
Let me turn the examination on myself and try to answer "Why did you go along with yo "mama's club" for about 20 years?
Let's see:
1. I was raised to be an obedient and respectful kid. I wasn't PERFECT, but I wasn't a "rebel" or a "hell raiser."
2. I have always been somewhat gullible; it takes me a while to figure out that someone is trying to deceive me. (Believe it or not, this continues to be the case today. I compensate by being generally reclusive.) I believed in Santa, Jesus and Jehovah longer than I should have.
3. When my mom converted, she destroyed the family. Dad split, we ceased communication with all my "satanic" aunts, uncles and cousins. Thus my access to contrasting opinions was curtailed. I had no school friends. We moved from one low-rent hole-in-the-wall to another frequently enough that by the time I left High School I had attended a total of 8 different schools. I was never, in my mind, part of the "class of XX". I never thought about it.
4. ARMAGEDDON WAS COMING! (I told you I was gullible.) I learned that I had a share in a great life-saving work. I did what I was told to do.
5. If I ignored the pain, it was easy. So I ignored the pain, mostly.
How did I change my mind and eventually leave?
I began to see inconsistencies between what I was told "the world" was like and what I actually experienced. "Worldly people" weren't terrible; they were PEOPLE.
I began to notice the little mental manipulations and mind games that the Elders played. "Your sideburns are 1/8 of an inch (3mm) too long" was one example. Trying to use ME to hammer other JW kids was another: "Brother Natas, do you feel that Sister Sally's dress is appropriate for a Christian?"
(My answer was, "It doesn't bother me.") It was a LONG dress way back when long dresses came into fashion, and Sister Sally was an Elder's kid who was going to become a pawn in an Elder Pissing Match if I resplied any other way.
I expressed an interest in "serving where the need was greater," saying I would like to see better results from my door-to-door work and I was told by an elder that my motivation was incorrect. He might have been right about that. I didn't pursue the idea a minute longer.
Then I found out that one of the "six-month TRUTH BOOK wonders" in our congregation was a pedophile, and that cracked my cosmic egg. It took time, but I was finally OUT.
