|At some point [ I cannot say when] a family ceases to be real a family and instead becomes a litter.|
The term "sheltered family" probably doesn't even begin to describe the lifestyle and parenting of the Duggar family. I grew up in a "sheltered family," where, other than a few episodes of L & O SUV as well as the L& O mother ship that evaded my parents' censorship radar when I was at an earlier developmental phase than most conservative parents (my parents' politics aren't particularly conservative, but their parenting style would have to have been considered as such) might have allowed a child at my developmental level exposure to something quite so sexually explicit, but even those few episodes I caught were of a very limited number. Otherwise, everything I watched or read was essentially only with parental approval and based on my parents' decisions about was age-appropriate and what was in my best interests at a given maturity level.
My parents allowed my brother and me to visit friends, fully knowing that the friends' parents' standards of what was or was not appropriate might very well not have been identical to their own, but my mom says she felt it was a chance she and my father had to take. Children who are not allowed to play with friends outside the family grow up with limited ability to function in the real world. My mom tried to have other children play at our home more than we played at the homes of our friends, but my mom said that other parents would be offended if my parents had always insisted upon play dates occurring at our home. We weren't allowed, for the most part, to sleep at other children's homes until our late teens except for slumber parties, and even then only after a thorough vetting of the situation. Our friends were allowed to sleep overnight at our house.
I grew up in a controlled environment. The Duggar children, on the other hand, grew up in a veritable giant plastic bubble. The problem with constructing bubbles or walls or anything of the nature around one's children is, of course, that with a large enough group inside that wall or plastic bubble, it's conceivable that one is walling in someone potentially every bit as damaging to the ones a parent desires to protect as those one is attempting to wall out.
