Now, I am not known to be in favor of monogamy, or the traditional family, or Christianity. And the concept of "children as ammunition" is indeed creepy as hell to me. And frankly, if the children of the Duggars grew up to become high-earning porn stars and strippers and video game designers, I'd laugh horribly at their outrage.
That said, however:
There is no single model on how to 'correctly' raise a family. I prefer – as I have explained on this thread several times – families with one or two children because I think that children deserve parental attention and mothers and fathers need to be available to grant it. However, in my view, none of the different models (unless actual child abuse is involved) should be illegal, or 'shunned'.
The idea of militant atheism – WHAT? YOU DARE TO BELIEVE THERE MIGHT BE A GOD AND OBJECTIVE MORALITY? WHY YOU HEATHEN DON'T YOU KNOW ABOUT THE INQUISITION AND GALILEO AND YOU HATE WOMEN – one where you condemn people as fools for believing in different concepts than you do is entirely foreign to me. The idea that people are somehow made less competent and intelligent than me because they have weird beliefs is distasteful. Its final result (though I am sure tyme does not personally intend on this) is anti-cult legislation like France and Germany already have, to suppress not just religious groups like Scientologists, but 'evil Evangelicals'.
My disagreement with the sexual habits of the Duggars is not as much a moral condemnation – I am, in fact, sex-positive enough to realize sex habits are not a questin of morality – but rather a pragmatic one, based on my belief that this is not the best way to raise children who will be free citizens in a Republic.
Reasonably, if I am to support homosexual marriages, open relationships, polygamy, swinging and strippers running for office (all of this I have supported previously on this forum), and reproductive choice, there is no escape from supporting the reproductive choice of the Duggars, even as I suggest it to be an inferior manner of raising one's children.
Consider a gun analogy: I support people's right to bear arms. I would like gun laws to go away. I may not subscribe to the notion that a 10.5” .22LR rifle mounted in a wheelbarrow is an adequate sniper weapon, but I would never dream of opposing your right to utilize that as your means of home defense. I would say it is a bad gun, and it might get you horribly killed - but because I support your right bear arms, even guns other the ones that make sense, there would be a natural limit to the moral indignation I express based on my tolerance and acceptance of your individual liberty.
