The point here is not to debate Quiverfull or the Duggars, but just to set clearly in people's minds the type homeschooling family being discussed in the article. I will not be writing a point-by-point analysis here, but I do want to set out my general responses:
I now many of you will argue with various of my conclusions--that's your right. But I stand by my comments. Yes, there can be a big poor family that does homeschool well, but it doesn't happen very often due to the amount of work it takes to keep such a family going. There can be well educated homeschool parents who don't care if their kids learn.
My strongest disagreement with the author is that YES it IS a freak fringe that is doing the damage. Trying to live in isolation is not healthy. Homeschooling certainly can be a very healthy upbringing when it is not used for religious and political indoctrination or even brainwashing.
