“Firstly are you saying that ALL the girls out of school are in this situation?”
No, but I think quite a few of them are (or at least in a case very similar).
“Secondly, why hasn’t anyone intervened till this girl has gotten to this point in the scenario?”
Cuz the system doesn’t work, remember? Nobody cares.
“Thirdly, I would definitely talk to the young lady in question, and no I can’t tell you what I would say to her because it would all depend on her situation, why she lost her interest in Judaism, when it started and why it started. I have worked with many young people in various situations caused by various reasons. And for reasons only they know, they clicked with me and trusted me.”
That sounds like a rather vague plan, at best. Not something that I think most mechanchim would buy, and not something I’d be happy to hear from my own child’s principal. A threat to the other students must be dealt with.
