I generally agree, with all of this, though still think it's funny how squicky people get about discussing sex with kids in general. Like, yes, nobody is teaching kindergarteners about safe sex or sex toys or positions or anything explicit about the act. But kids from a pretty young age are completely capable of learning about the fact that it's a thing, it's (usually) how they came to be, and that it's a very personal subject that they themselves have control over regarding their own bodies. The more educated kids are about sex, the less likely they are to make risky decisions or allow someone to "groom" or otherwise take advantage of them. Actual "groomers" love it when young people are uneducated in the matter. And as for the whole "why would an unrelated adult want to talk to kids about sex, that's the parent's job" argument, most sexual abuse of children is perpetrated by family members, not teachers. The teachers are more likely to stop it than family is.

It's weird how there is this major, almost ubiquitous, often risky factor in life that we often attempt to completely hide from children until they stumble through it themselves unprepared. All because people are either so afraid of being seen as the "creep" or "groomer" or so afraid of the idea that their children will be doing it themselves someday, which ironically, is something they also pray for in the form of grandchildren.
