“defender of truth”: “. . . it would be best to acknowledge his comment and offer to consider the matter with him seperately after the study.” “But since that is your personal question, let's wait until the end of our reading. Then you and I can discuss it together." It is often possible to arrange to conduct a personal Bible study with interested ones at another time and in a different setting.”
This is obviously a policy to discourage any kind of consideration of any information or opinions outside of the Watchtower Organization’s own unique curriculum. Also, conducting Bible studies separately one-on-one in isolation from the rest is to prevent the subject (student) from being able to compare their reaction to some else’s. (It’s similar to when people in a group of suspects are separated when being interviewed by a police detective.) Nothing like personalized attention to effect the process of brainwashing (indoctrination).
