To become a JW in good standing is to become cattle in a herd; docile, manageable, and utilitarian.
In a word: mentally "Lazy."
It takes enormous effort to allow the foundation of your world rug-pulled from under you and to regain your balance as you re-order your entire mental universe!
Basing everything not just on a book (Bible) but interpretation of it - disallows the clean slate of apostasy. Who will interpret your abandonment, rebellion, restructuring in a meaningful way?
Communists and JW's live in an ordered Universe where everything which isn't commanded is disallowed - and *tergiversation is certainly disallowed and punished. (*desertion of a cause, position, party, or faith).
Personally, I'll not soon forget an overwhelming feeling I discovered within myself upon visiting a UNITARIAN church.
After two hours of services, as I was walking out I turned to the friend who'd invited me and said: "I don't think I can handle this."
My friend said, "Why not?"
I replied, "Because you aren't against anything."
I suddenly discovered I needed to strike against something "wrong or bad" and there just wasn't any target. Consequently, no purpose in going to church. This impulse was bred into me by the JW's!
I had no craving at all for fellowship itself.
Wow.
