Readynow: If simply hearing the words “yiddishkeit is THE BEST” would stop Jews from going OTD, there wouldn’t be any OTD’ers in the first place. I believe the problem is the OPPOSITE. Intellectual Jewish children are being propagandized from birth by uneducated teachers about how great Judiasm is, without explaining to them the whys and hows. These children, as they progress into adulthood feel like their religion has all the same qualities of all the religions they’re supposed to denounce.
Wild and hyper active kids go off for different reasons, most probably because no one in the education system has the time and patience for them. At least where I came from, the motto was always, “If you don’t like it, LEAVE!”. There’s not enough competition, as the religious population keeps on expanding, there aren’t enough schools around to give the big ones competition. There’s nothing keeping such schools in line.
