One of the greatest challenges and stressors I faced growing up was school. I was sent to a public school, surrounded by a bunch of people who were going to die because they were evil. Imagine an 11 year old child being the only person on campus who was chosen to know the truth. An 11 year old child who knew much much more than all the adults who were entrusted by his parents to teach him.
What possibly can be the result of protraying all the educators and other students as pagans who deserve to die, yet as a student, you are expected to outperform the other children and be a good representation for Jehovah's people? What kind of person will that child grow up to be? Or better yer, what kind of person will that child grow up to be if he does not have a family who is part of the "in" group at the Kngdom hall? What will happen to that young man if he does not hold enough favor with the local elders and ministerial servants and therefore not offered a job with other "ins"? What will he do when he is faced with the harsh reality that most adults have to live and work in the pagan world and it's demonic influences?
