Another explanation is how children are treated...like little adults. They are encouraged to take stances that no normal child should even think of, to pay attention and comment at meetings like adults, and to behave and be as responsible as adults...That includes knowing everything to the letter about doctrine. Even if...ESPECIALLY if...it will give the kids nightmares.
That's what I think. And the pressure is put on them to get baptized at an early age so they can be "servants" of Jehovah--when they are not ready for. Thus the pressure is on not to commit a "sexual sin" for fear of being disfellowshipped.
