So can we decide whether one approach is better than the other?

It is very important to note that debates about research into the effectiveness of different types of sex education, and criticisms of the extent to which programmes contain factual inaccuracies and are guilty of stereotyping, do not always represent objective attempts to weigh the evidence that these studies have produced. While the debate between supporters of both approaches has populated these areas of difference it is not in pursuit of a resolution of their differences but rather a definitive answer that suits their moral agenda. There is no doubt that, whatever evidence is assembled, people who hold particular strong moral views are unlikely to give up supporting their preferred approach regardless of whether it works or whether someone else thinks it presents a distorted picture of the facts.
