rebdoniel, while you may have “easily adapted”, for most people it is a gradual and difficult process. Furthermore, since you chose this lifestyle voluntarily, you may have difficulty understanding why people would discard it. However, it’s very easy to take what you have for granted. The grass is always greener.
I would also add that there are plenty of frum parents who did everything right and still ended up with children who smoke, have sex, or are “at risk” in other ways. It’s not necessarily a side effect of public school or a secular upbringing. My husband went to public school and never did those things.
