There are a lot of lessons to learn but no one really wants to know, because no matter what people in the know say there are always going to be detractors who are going to keep saying that OTD is a choice, yada, yada yada. And keep blaming the kids for not being taught to have a love of Yiddishkeit, a love for mitzvos, midos and maasim tovim.
They are still going to blame kids for not being old enough and mature enough to handle their own pain and their own questions. Enough said?
