'FaFo' is shorthand for 'Fuck around and find out', yes? I'm not sure this internet tough guy approach is going to persuade anyone.
The school provides a good space to learn something a bit more realistic about sexuality at the appropriate ages. But of course as a european I know that the US in parts has extremely prude ideas (your censorship also affects us).
That being said, there are many modern nations where kids learn about sex in school for a while now, and they didn't develop psychological trauma or anxiety because of that (quite the opposite). It isn't as if there are no studies done in that field.
But prude morality seems to trump everything. Some don't seem to realize that supressing sexuality is something religions tend to do for a reason (and it is not the good of their hearts).
