Abstinence Only

I understand that people have a lot of mixed feelings about the effectiveness of abstinence-only curriculums in American public schools. I happen to think it a terrible idea, akin to closing one's eyes and hoping things just get better. But I would hope that certain aspects of the Texas textbook debate would embarrass even abstinence-only advocates:

For example, one textbook under review advises that a good way a teen-ager can prevent a sexually transmitted disease is to get plenty of rest so he or she can have a clear head about sex and choose abstinence.

Unbelievable.
