I'll start the ball rolling. Dealing with KIDS in any type of judicial manner. I would do everything I could to get parents to "deal with it-kindly" at home. I never disfellowshipped a kid, but knew a number of congregations who did. It scarred kids for life. It seemed that most of the time the acting out was from something else going on at home, or school, that was unknown. If a child is acting out enough to tell the Elders, they need therapy from a PRO. I have lost sleep over realizing I should have asked better questions from certain kids acting out..because I found out later they had suffered some form of abuse or mental health issue. An hour in the library with the "brothers" does not help those issues.
Having been a parent..I understood the "fear factor"& leverage of the "3 Bears" but I always felt it was mentally and emotionally abusive to use that forum with kids. Disfellowshipping and Public announcements are wrong for 95% of adults..for kids..it should be a CRIME reported to Child Protective Services.
