It's hard to be a kid among Jehovah's Witnesses. There are five meetings a week, door knocking and strict discipline. Consider this quote from the February 1, 1956 Watchtower on page 95.
"Modern parents, in this age of delinquent youngsters, can take a lesson from the mother "teddy bear," the koala. When baby koalas "are really naughty," writes Ivan T. Sanderson in his new book Living Mammals of the World, "the mother turns them over her knee and spanks them on their bottoms for minutes on end with the flat of her hand, during which time their screams are soul-rending."
This next quote from the February 1, 1960 Watchtower on page 80 is far more sinister.
"There may be rare instances where a child is so hardened in its stubbornness that even the rod of correction cannot drive it out. In the days of Israel parents were instructed by Jehovah to take such a rebel to the city fathers and they, in turn, took the incorrigible one out and stoned him to death. There were no juvenile delinquents under such a system. (Deut. 21:18-21) So also today, the New World society of Jehovah's witnesses can not and will not tolerate juvenile delinquency to exist in its midst."
Just to be clear, they are threatening disfellowshipping and shunning, a type of spiritual death, in their view.
