I have many Iowan friends, and NEVER met anyone like that family. They seemed very nice, but I personally think a few screws were missing somewhere. I got the feeling that the parents were extremely controlling of the kids in order to get 'free' labor on the farm. I do think the kids are missing out on a whole lot of education and social interactions that they will need as they are older. The mother is absolutely OBSESSED with food and the 'end of the world' paranoia, yet she seems like such a good hearted person.
No, their lifestyle choices wouldn't be mine, but to each his own as long as each is individually informed/taught to MAKE their own choices. That is what I felt was lacking. But again, with media coverage - who knows what all went on or was said. It could be distorted dramatically as so much of our media is today. Hence, I will withhold judgment (i hope).
