Comprehensive sex ed saves lives
Comprehensive sex ed reduces HIV transmission and delays sexual activity. A good sex ed class scares kids straight. It says, “Sex is nice, but it can seriously mess you up if you abuse it. Here's what can go wrong. …” You learn that there's no such thing as safe sex, but safer sex is possible.
This is why science classes teach science. You start throwing ideology around, and the whole thing falls apart.
The APA recommends:
Only those programs whose efficacy and effectiveness have been well-established through sound scientific methods should be supported for widespread implementation.Duh!
New programs to prevent HIV and sexually transmitted diseases among youth should be tested against those programs with proven effectiveness.
