I think you missed the part where I said unsafe sex. I'm trying my darndest to find where I said abstinence, but gee golly I just can't do it. But I guess it just has to be someone else's fault somehow.
You said: "Unsafe sex at an early age is just plain a stupid dangerous decision, and there's plenty of people to tell you that." In the US there are major political lobbies whose goal is to prevent kids from hearing that in favor of abstinence-only. You can't just gloss over that and say that kids should know better when people are actively trying to keep them ignorant.
