Knowing why kids go off is not only advantageous for one who wants to help the kids, but also for one who wants to prevent it.
Therefore, if I believe that kids go off because their parents are obnoxious, and as such I make an extra effort to break any obnoxious habits I may have, and Yankel Shmerel believes that kids go off because there is too much pressure, so he eases up on the pressure, and Hentcha Genendel believes that kids go off because they aren’t taught enough about certain things, so she teaches her kids these things, and so on, what’s to lose?
My point is that it’s worth everyone spouting their boich svaros because while it might not help much in the quest of bringing people back, it does have an impact on the way people think, and causes them to think more about their behavior in the future, thus avoiding the issue to begin with.
