PickieChickie--You might want to check with a mod but MercyNeal and I were just reminded on the Ayres thread not to post comments from other sites. We were told all we could do was post a link and a description of how to find the comment ie. date and time and poster. Just a head's up. The comment is quite scary, isn't it? All of those comments are worth reading.
The link to the poster's name which you added is an exceptional site with lots of great info. I don't see Michael Pearl as a "new" guru", though. He's been writing about his vile and cruel discipline/abuse for years. I wonder if the above comment means that a whole new subset of parents have discovered him? That would be frightening.
As the mother of a huge family, I can attest to the fact that discipline (not abuse) and order are necessary for any quality of life. One must have "systems" in place and natural and logical consequences for all positive and negative behaviors. I fully understand the quest for anything that will work as without a system, you have chaos. Thankfully, we had access to seminars and trainings sponsored by agencies geared at special needs foster and adopted children. These trainings could never include any sort of physical punishment, isolation, or emotional abuse.
We had to learn to be VERY creative and consistent (much like a public school teacher would be). It can be done but it's also quite easy to get overwhelmed. I worry that many who choose the Quiverfull life, might (please note I said "might") get overwhelmed once the children start to develop their own personalities and some become strong spirited. Not every child is compliant and willing to go along with the family style. It makes me physically sick that Michael Pearl is standing by, at the ready, to tell you what to do with that plumbing line in order to keep that strong spirited child in his/her place.
FWIW, that's one of the most interesting perks of having a large family. You get the joy and challenge of raising children with every possible quirk and style.
