Zahavasdad:
A cursory examination of the above discussion leads me to take issue with some of your earlier statements, I hope in a non-offensive fashion.
Whilst I admire your concern and positive outlook on the behaviour described in the OP, which seems sincere and well meaning, some of your justifications seemed far off the mark.
Firstly, if I may ask directly, do you honestly believe that the fact that he may have kept awake others by talking in any way mitigates watching inappropriate content (I will assume LF was accurate in that aspect)? It’s not an either/or. And your attitude towards ‘chareidim’, and seemingly overly harsh judgement of their behaviour speaks for itself.
But what really bothered me was the attitude towards tochacha. As a side note, one should give tochacha if the giver believes it will be well received. In this case, I doubt it would have. But bringing up instances of poor chinuch, ostensibly leading to teens going OTD, as a way of writing off tochacha and aspects of the chinuch system completely, is pure straw-manning. Of course, in the examples provided the mechanchim in question did the wrong thing, but that doesn’t mean mechanchim in general shouldn’t try, in the correct manner, to help their charges face these and similar nisyonos.
