I signed the consent form for my 7th graders.

But they didn't learn anything new because I'd already taught them everything. They clearly understood the biological differences between boys and girls. They understood where babies come from and how a man and a woman both required to have a baby. They knew about how sperm fertilizes the egg, etc.

I've never implied a problem with sex education for children. But I decide what's appropriate for my kids, not you. And it's sure as shit not ok for a teacher to make that decision for me, and then keep a secret to hide it from me.
