One other aspect of abstinance that we're all missing is the HUGE increase of STDs among teenagers. In my wife's office, they see increasing numbers of them, along with pregnancy, and it's alarming to be sure. Compared to just a few years ago, the numbers are staggering.
This isn't a right verses left, Christian vs. atheists, it's protecting your kids and teaching them right from wrong. Most people are far too concerned with who's doing what and which political party is correct than dealing with the real problem, which is disentegration of the family unit, and truly crappy influences on TV and internet. Most parents would prefer others talk to their teenagers about this instead of standing up and taking responsibility, like everything else in their life.
We're dealing with this issue right now (16yo and sex, not pregnancy), and its not brain surgery people, its being involved in your child's life. Sure it can still happen, but how many of us are lucky to have survived our teen years upbringing or not?
Last comment and I'll get down off the soapbox. As to the Republicans announcing this, if they hadn't, the Dems would have been screaming that it was covered up. It was a no-win situation and better to announce it early on. Both sides have plenty of crap and not a lot of substance yet, and the news networks would rather focus on a 17yo girl getting pregnant than a detailed energy policy from either of them.
Rant off, back to your regularly scheduled debate...
