I grew up mo. It is SO not true that this lifestyle leads to going off the derech. How ridiculous!
I happen to have become more frum out of choice. Although my mother only covered her hair in shul, all of us (daughters) cover our hair fully, all the time. My parents kept taharas hamishpacha. None of the girls I went to school with except those on the serious fringe of frumkeit TO BEGIN WITH (the one and only who left a frum school to go to solomon Schechter) went off the derech.
I think this thread has caused more ignorance and damage than good.
Truly, the most ridiculous part is those who have no knowledge first hand of modern orthodoxy commenting on it’s effects on frumkeit
