It *is* sad, and it often becomes a self-perpetuating cycle. The stigma that perhaps used to stave off some of those behaviors has been largely removed by the 'don't judge anyone, ever' mindset, and the fact that we've created systems that serve as safety nets, while well intentioned, probably contributes to the lessened 'fear factor' that girls used to feel.

I think there is also a mindset among many families that teens can't be stopped, anyway, so there is no use in making moral judgments about teen sex. I really think a mindset has to be put into play for kids when they are very young so that in their very subconscience, there is a mindset that says, "That's not something I'll do"... just as we do regarding drugs, stealing, being violent with others, etc..

At the heart of it all is the fact that there is a baby who likely won't be receiving all the influences a child needs to develop well emotionally. Little girls who grow up without strong fathers around are more likely to look for male attention in sexual ways as they hit puberty, and boys who grow up without strong fathers are apt to struggle, as well. We don't do our society any favors when we treat this issue like it's no big deal.
