I want to make it utterly clear that I have lifted any and all contempt I've ever had for Bill Gates. This has been made easier after he stepped down from Microsoft, having fallen short of his bid to take over the world. It appears now that he's intent on saving it instead. Observe.
Now I've made my position clear on abstinence-focused prevention. But what Gates attacks it at a different level, his argument commanding assent. Good one, Bill.
