And this is why things won't improve anytime soon on the teen pregnancy, sex trafficking or STD side of things: sex has lost its sanctity. It is considered merely a bodily function with no social responsibility attached to its indulgence beyond obtaining consent (to the best of ones knowledge) (and maybe a condom) before enjoy it.
With regards to teen pregnancy and STDs, you know what is incredibly effective? Education on safe sex. You know what is not effective? Abstinence only lectures.
You have an unhealthy view on sex. For you, sex is a sin and is immoral if it is done for any other purpose than procreation. You think somehow your view is morally superior than everyone else's. The fact is, your view is ignorant of history and it is ignorant of reality. And for all of your supposed morality, what you wind up doing is you unintentionally promote teen pregnancy and the spread of STDs to teens.
