For the record, teens getting pregnant isn't a NEW trend. During my grandparents' youth, many teens were not only getting pregnant, they were getting married, too. One of my grandmothers never finished school. At the age of 14, she left home and school to start a family, marrying my grandfather. They had a happy marriage. I love to talk to with people, especially the elderly. I find that they are very honest. I often ask them to tell me about meeting their spouse, smoking, and other things which are probably off limits to most people. I find that an overwhelming number of the people I ask, were married or pregnant as teens. Most of them seem to be very pleased with THEIR life choices. ;-)
With five kids, somebody in Palin's family must be having good sex.... oh, sorry. I now see the word, "scandal."
Yeah, but during that time, the teen years were more borderline adult years. Now, sociologically speaking, teen years are associated more closely with childhood and it's not until people are in their 20's that they get the chance to be considered adults.
Typically, the religious views behind pro-life also push for "no sex until marriage" and this doesn't obviously isn't the case.

Yes, some kids have sex no matter what, but IMHO, this is also the result of a too busy, overachiever mama who doesn't have time to connect with her teenage daughter issue. I'm not even gonna mention the need that the baby has for his mother, especially with DS and she's obviously so busy that her position takes her away from her child at 5 days.
I'm not either pro-life or pro-choice, as I see both sides. If Roe vs. Wade had been a year earlier, there would be no OrganicMama, but I do not agree with the extreme viewpoints of the pro-life side. The issue lies much earlier and deeper than that, something that I don't think the religious right wants to deal with, like openly teaching our children (especially daughters) about respecting their bodies and about simple biology. Teenage sex will still happen, but at least the informed knowedge & choice is there.
Feeling bad for Bristol and the rest of Palin's kids right now. An uninvolved, extra busy mother leaves plenty of room for things like this.
