It makes me frown. It doesn't do any good from no matter what angle you look at it (mathematically, psychologically, financially, etc). For one thing, the human species is suffering from serious overpopulation. We don't have enough suitable parents for all the children we have already. Kids who need parents (heeeello, even in Ameruhica) are passed up for the sake of having your "own" baby (I'm a srs advocate for adoption, can you tell?), the only difference being genetics. We have so many people, that we have to destroy natural habitat in order to farm and raise mass quantities of food in order to sustain us! And you think, in spite of that, at least a 1/3 of the human species is starving, anyway. My biology teacher talked about humans not yet having reached carrying capacity. Personally, I don't think we ever will. We'll just continue to tip the scales in our favor, destroying whatever we need to in order to perpetuate our population problem.
Also, people have kids they can't afford. Nearly everyone in America is already in debt, before having kids. And there are people having 18+ kids? I think it was the Duggards I saw on Oprah, and they were perfectly up-front about the fact that they depended on the geneorosity of third-parties to feed and clothe their children. In the case of adoption, if you can't afford meeting the needs of the child, you don't get to adopt it. It's easier for the adoption system to select appropriate parents than it is for DFS to remove children from unsuitable homes. My point being, people can have all these kids without being able to afford to and get away with it. The Duggards also admitted that their older children raise the younger ones. I think that speaks for itself, when you can't even afford the TIME it takes to adequately raise a kid (and parents wonder why they end up with such brats for children).
Not to mention that most of the time, the reasoning is "Well, if God didn't want me to have these children, he'd slip a magical, omnipotent condom on my husband." You know, I have no issue with a belief in God. That's fine. What I can't stand is using your belief as justification to do completely illogical and often harmful things. Believing in God is not an excuse not to make educated decisions. And you know, I REALLY doubt he has enough time in a day to concern himself with your sex-life, anyway. Some people get this mentality like, "If the Bible didn't explicitly tell me to, I'm not." Which is a whole 'nother can of worms in itself, but God not personally telling you to use contraception isn't enough of a reason not to.
