right. It is a difficult balance – if you introduce, esp kids, to the world too early, you are risking OTD, or at least acquisition of undesirable views and middos. If you don’t introduce at all – then R Soloveitchik’s question from the 1950s still stands: if we claim to have truth from Hashem, why are we hiding in caves.
Middle road is hard.
