I have read articles that say that Abstinence doesn't work in stemming pregnancy and the spread of diseases like AIDS, and other STD's.
What is perplexing is that the language is wrong. I say that Abstinence is 100% effective in preventing these things. At what point does "not having sex" gets you pregnant?
What fails is really the human heart. It is humanity that is fallen, humanity that is imperfect.
Safe-sex and condom use is a secondary barrier. It is a secondary defense against the fallen human nature.
Abstinence has the power to wipe out AIDS in a single generation. Not only AIDS, but syphilis, gonorrhoea, and a host of other STDs. There are still 3 other incurable STDs, Hepatitis B, genital herpes, and Human Papilloma Virus.
In one single generation, AIDS could become a distant memory; and the power and responsibility is in the hands of everyone. You and me. Not the government, not researchers, not social workers. And the cost? Zero. Not a single dime need to be spent to hire researchers, do clinical trials, etc.
Perhaps one reason why people perceive that abstinence is a pie-in-the-sky goal is that of the perception of society around. They say that teens cannot control themselves. They say everyone around is having sex, you can't stop it. The message of abstinence isn't to not have sex. It's to not have sex until you are married and faithful to one partner.
If we liken it to another habit, spitting, perhaps we should say that Beijing is wasting its time trying to educate people not to spit indiscriminately and issue portable spittoons to everyone in China. Let's practice safe spitting. After all, everyone in China spits. We can't help it.
