The Duggars do seem like a nicer family than most reality families. I do agree that they all seem pretty happy and well adjusted. However, the face shown to the public does not always reflect reality. Just recently, the blonde gal from Extreme Home Makeover announced that she had been suffering from intensive depression for years, all the while smiling like she was the most upbeat, cheery person on earth. The fact is that after researching the Duggars and their beliefs, I became a bit turned off. That Gothard person they follow is a creep. They also believe in blanket training which essentially involves training a baby to stay on a blanket for long periods of time by placing them there with toys, and then smacking them with a wooden spoon whenever they try to get off, graudally increasing the time they must be on the blanket until they know to stay there. Look it up. The Duggars don't mention corporal punishment much publicly, but they have in the past and if you read their book, that's what they mean by "correction". Watch the show carefully and you can sometimes see that with a whispered word or two, Mama Duggar can instantly control a crying toddler who wants to go with her to the store, or something. Watch also how the older kids quickly surround the child, IMO to cajole the kid out of his or her mood so the kid won't get "corrected".
I also have a real problem with the Quiverful movement. Children are wonderful. BUT, in this day and age, overpopulation is the root of all of our problems, from the amazing strain on our natural resources, the impact on rapidly disappearing and polluted natural areas, wars, which are really just people fighting for resources, etc. Just washing cars, doing the wash, watering lawns, causes our oceans to become filled with dangerous nutrients and pesticides which is causing huge dead zones in the oceans around the world and ruining our fishing industries and the wild animal populations that eat ocean fish (whales, sea lions, otters, etc). The Duggars are refreshing in that they break the mold from the rest of the reality families. They seem moral, simple, and to really be about family. But, I don't think they should be a role model for the rest of the world. There is a huge price to pay for such large families, in terms of impact on the kids themselves and impact on the world at large. JMO.
