It's funny to me how they're such a religious family.
And that religion frowns on sex so much.
Yet she popped out 18 babies.
Where do babies come from?
Sex.
Religion doesn't frown on sex. Quite the contrary, most religions encourage large families.
"Be fruitful and multiply" and all that... (GEN 1:28)
What many of them object to is sex for fun... sex with no intention of having a child as a direct result.
...and a few of them are essentially OK with that, as long as you occasionally have kids.
Speaking from a Christian standpoint (though not from a sect that is as...strict...as the Duggar's), I don't believe that sex without the intention of having a child is frowned upon. Generally, it is only sex outside of marriage that is discouraged. Sex is encouraged, though, as a way of bonding between a husband and wife. If you read Song of Solomon, it is pretty racy (at least racier than one would expect for the Bible) and, to the best of my knowledge, there is no mention of children in the book. I think it is a common misconception that 'religion' condemns sex. There are just guidelines as to when and with whom it is appropriate.
I went to a Christian school from third grade to the time I graduated and we were never given any impression that sex is wrong (within the right context). I know many people on here seem to frown upon abstinence teaching or the "no sex before marriage" thing, but I don't want anyone to think that kids who grow up with Christian backgrounds automatically think sex is wrong or gross in any way. Most responsible Christian organizations simply present the way they feel one should go about it. Having said that, I am aware that there are severely legalistic sects of Christianity that may give children an unhealthy impression of sex. However, those organizations rarely represent the majority of Christian denominations.
And to my opinion of the Duggars (because I am a little obsessed with them): They are supporting their family with no help from the outside sources (to the best of my knowledge). They aren't hurting anyone so if they want to have litter after litter, then whatever. To each their own. I will say, though, that Michelle is at an age where complications are more likely for both she and her child. I don't think any of her kids have had any health problems, so they have been fortunate enough to have so many healthy children, but I think that having any more children at her age is a little risky.
My major problem is the way they are raising their daughters. It seems as though those girls are being raised simply to be wives and mommies and not being presented with the possibility of doing something else with their lives. Even if they did get a higher education, would they use it? I know the oldest son's wife said she would not get married until she finished college. She did and where did it get her? Will she ever use it or is she simply another Duggar baby-making machine, now? I have a feeling that the Duggar girls are going to follow in their mother's footsteps (which is fine if that is what they choose) because they are unaware that they are capable of anything else.
