Good point. Let me fix that:

Well, in fairness, the religious right opposes the HPV vaccine based on a value difference, not a factual difference. That is, even if all the facts about the vaccine and its effects on sexual behavior are agreed upon, there is still a value dispute about how society should deal with sex. Many on the religious right oppose the vaccine because they don't believe in treating the risks of sex as medical problems that can be prevented, even though they don't challenge the scientific facts about the vaccine.
