Seventeen-year-old Bristol Palin is pregnant, and now we learn from sundry news sources that her mother, Alaska Governor Sarah Palin, supports abstinence-only education (or did, at least, in 2006, when she answered a survey question to that effect). The supposition by some in the media is that the foolishness of abstinence-only education is somehow proven by Bristol Palin's pregnancy. Thus, we hear, schools must offer sex education in the classroom. This presumes that Bristol Palin--had she only been enrolled in such school-proffered sex-ed classes--would have made different decisions. Which further presumes that Bristol Palin was several months ago unaware of the existence of contraceptives or could not procure them. Seems a stretch.
