This article gets at the idea that increasingly, put all sex ed aside, we are uncomfortable with the basics of the birds and the bees. Ie. we don’t want to acknowledge where babies come from.
Yes, we are increasingly uncomfortable with where babies come from, no doubt about it. Our lingo betrays us. And it doesn’t take a social conservative to perceive it….
Fully autonomous. In other words, free from embeddedness in relationships. By extension, having little to do with moms, dads, and babies. See what I mean? We’re ambivalent about the procreative aspect of sex. Sex is rather all about pleasure, or, to use the lingo of a public-health friend of mine, all about the f***ing. (Forgive my being blunt and crude, but if the shoe fits . . .)
This is the underpinning of the pro-choice mentality. I can have sex, but I must not associate that sex with even the possibility of a baby. Ironic, even, since these are the folks who are so very concerned about “sex-positive” and all that jazz (what does that even mean?). But get down to the basics of the birds and the bees and they are in total denial.

Last sentence in Regnerus’ article begs for an edit. “We are a strange people” is polite. We are a depraved people would be closer to reality.
2 Peter 2:17-19 These people are springs without water and mists driven by a storm. …. 18 … by appealing to the lustful desires of the flesh, they entice people who are just escaping from those who live in error. 19 They promise them freedom, while they themselves are slaves of depravity—for “people are slaves to whatever has mastered them.
