Brooklyn19,
“the part about looking into what makes kids go off. (you can probably spend every second of your life on that one and not even come close to the answer. there is no answer.)”
You are wrong, in most cases there are answers and in alot of cases they are the same as eachother.
There are books on the subject with interviews of the kids themselves as well as people who deal with kids at risk or who went off the derech professionaly.
Nowadays many people who went off the derech even have blogs were they state clearly WHY they went off the derech (and most of them are for similar reasons)
Bkitzer if somone really wants to know why kids go off the derech they really really can find out.
