I've been trying to put myself in my parent's shoes.
I really think that apostate's families (and friends) actually would prefer us to fake it. They fear having to make that choice between us and the organization, and they would rather us pretend for their sakes.
I truly believe that the only thing holding the organization together at this point is fear.
If all the doubters didn't have the fear of losing their family, they'd come out of the closet. If their family wouldn't be required to shun them, then they'd be able to share with their family TTATT. True, not everyone that hears TTATT will wake up, but I truly believe that without that fear factor, the vast majority would.
Once you remove that fear factor, more people leave, more people wake up, and the organization starts crumbling.
That's why I truly believe they will never "repeal" the shunning practice. The reason they re-instituted it to begin with was because of the hemorrhaging losses in the late 70's and early 80's.
Fear of being shunned is the only thing holding this organization (as we know it) together.
