I think it's more about the way things are vs the way things "should" be.
e.g "teens are going to experiment with sex, so comprehensive sex education is the best way to keep them safe"
vs
"Teens should not have sex, so abstinence-only education is the best way to keep them safe"
"The purpose of a system is what it does". Dangerous principle to apply too literally but almost always worth considering. In this case, the purpose of abstinence-only education is to increase teenage births and the purpose of modern sex education is to decrease it.
