Embedding Christian morality aka eusocial goals in sex ed would be a bit too insensitively "dominionist" and intolerant of other worldviews.
Instead, we're literally just fucking around. Sharing statistics with kids that can't master arithmetics, showing scary pictures of what happens when you don't use protection (don't worry about how to choose partners wisely, slaves). Just fucking around. With your children's minds. With your tax dollars.
Casual sex is for faggots. #IgnoreSodomiteOrders
