They don't look corny at all to me, but then I was raised around families like that. I don't "get" the hostility towards this family. I have watched the show.
The kids are not lacking in their education, being homeschooled. I would bet that they will be as well, or better prepared to deal with the real world than many of the graduates of the public school system. The older ones were all involved in the house building. They have schooling in the arts, play musical instruments, and I think I remember watching that they have a tutor teaching them a foriegn language. (I might be confusing that with another show) Just because they dress like Mennonites, and refuse to conform to societys fashion standards does not mean that they are weird, odd, whatever.
The parents do not believe in birth control. That does not mean they are sex maniacs, humping at every opportunity. It means they have a loving, healthy relationship, and do not use b/c. Good for them! At least their kids are not latchkey children, like many families today... off doing who knows what, on the streets with no supervision.
I am so surprised at how folks want to judge this family. The kids are learning responsibility, just like any children on any working farm, etc. (the family IS a work in progress.. a working family) would learn. This is not child labor. This is good for them. Just because they are different than our families does not make it wrong.
If that is the case, then many of my own relatives, including my mothers family is wrong. Weird. Etc. It just is not so. A large family like that can function beautifully and produce responsible adults who are productive members of society.
I tried to get to the Duggar website, because I am sure they answer many of the questions you all have about them. But... the website must be overloaded with the latest interest in them, because I was not able to get to it.
