There is not and has never been a law or court case that mandates what any parent teaches any child at home about sex or whether they do so. That sex ed is taught in the schools is only a supplement to what is (ideally) taught at home.
The numbers do not shock me, I am quite familiar with them.

The teenage pregnancy rate in this country is at its lowest level in 30 years, down 36% since its peak in 1990. A growing body of research suggests that both increased abstinence and changes in contraceptive practice are responsible for recent declines in teenage pregnancy
The tables show that the pregnancy rate for women ages 15-19 and ages 15-17 was substantially lower in 2003 than it was in 1972. The pregnancy rate was substantially lower in 2002 than in 1986 (and even more so from the peak in the early 1990s) among sexually experienced women ages 15-19. Unfortunately, the US still has one of the highest teen pregnancy rates among developed countries.
STDs are indeed a problem, which is why teens need medically accurate information about them and ways to prevent them----all ways to help prevent them, including abstinence, ways to have safer sex and the need to be extremely choosy in one’s sexual partner.
You are arguing against something I have never said. I advocate teaching about abstinence and holding it up as the ideal, but I also advocate doing so in the context of medically accurate information on all aspects of sexuality. That includes all forms of birth control (including NFP) and the proper ways to use them, ways to have safer sex, the consequences (physical, emotional, financial) of engaging in sexual activity, the fact that every form of birth control has a failure rate and that that failure rate skyrockets if used inconsistently or improperly, the accurate facts about ways in which STDs are spread, myths about sex (can’t get pregnant the first time, douching prevents pregnancy, oral sex isn’t “real sex” and doesn’t share diseases, etc)----all of it. Sex ed is not only for teen years, but for their entire lives.
Full information so that they can indeed be armed to make the “smart choice”----not abstinence only and leave all the other (mis)information to be provided by their friends in the bathroom who likely have as little factual information as they do.
