In response to a diminishing number of requests, let me state my opinion on class room sex education: although it's efficacy may or may not justify it, I have no problem with it. I grew up in a household with a copy of the Kinsey Report on our bookshelves so I may not be typical. But any attempt to gloss over the "facts" of human sexuality, to focus on abstinence only, is, IMO a total waste of time. I have never been much of a believer in ignorance as a teaching tool.
To suggest that Miss Plimsol putting a condom on a cucumber will get the kids "thinking about it" is absurd. The kids are "thinking about it" (and far too many of them are doing something about it) 24/7. We live in a culture saturated with sex, and there's no going back. So clinical descriptions aren't going to impress youngsters who can spend all day long on porn sites if they want. Or who send "sexts" with their naughty bits exposed. It may just be, however, that some kids (who think they're so d*mn smart about everything) might actually learn something that could prevent a pregnancy or STD. The "values" abstinence only types want to instill, while important, are better left to family and clergy.
As a doctor's kid, I'm a big believer in vaccinations. The "high ignorance" campaign against vaccinations by people who really should know better, is disgraceful. And puts at risk kids other than the ones not vaccinated. I'm old enough to remember the feeling of what a blessing Dr. Salk had bestowed on humanity with his vaccine to prevent polio. My old man gave me my injections in the kitchen, in return for which, he allowed me to give him the shots. The horror of polio has faded. But think of a perfectly healthy kid going out for a day at the community pool. Coming home complaining of sniffles. Going to bed and waking up the next morning paralyzed. That was polio. And every parent, every parent, was terrified.
