If the parents have an indifferentist outlook, how can the children be expected to know, care or believe in their family's nominal religion?

OTOH, if a parent's grip is too tight, kids may reject religion as form of rebellion. I've seen a lot of that. Mostly due to outside influences, particularly public school.

Yes, it is a balancing act. There is the risk that children might reject their parent's beliefs. But hopefully at minimum they have some foundation, and something to return to later in life. Those who raise their children secularly are denying their children a whole dimension of life. Many of these children end up being victims of religious or political demogogues, because they seek something they are lacking inside.
