Aries, it still makes no sense. If it’s part of growing up, how come none of my kids or siblings knows about such things b”H? When I warn them about that, they don’t even know what I’m talking about. Only one brother had one sub (NOT Rebbe) who took kids on his lap. The only explanation I can think of is that your chevraman is himself a molester. Like some people with mental illness try to pretend that the whole world is mentally ill.
Another point. My father, a tzaddik of a yid, still refuses to believe that parental molestation is possible. He’s so far from such filth, he can’t imagine it happening. I’m sure many rabbonim are like that. We should try to explain it to them, of course, but instead of denigrating them, we should appreciate their purity, and the holiness of Klal Yisrael, that prevents them from seeing the truth.
