In case no one else noticed in Florida, people are going to have sex no matter what. Not telling them how to do it safely is kind of like telling all your pilots they can't have training, but knowing full well they will still fly the planes.
You're giving them too much credit, I'd say. It's hard to tell if this is 5d chess towards a conservative wet dream or just the usual christofascist nonsense. It sounds a lot like abstinence-only education, which has been a failing strategy from the Right forever.
The stated goal of abstinence-only education is that young people don't have sex until marriage. It fails at that. The (un)stated goal of the christofascists is probably keeping the future labor pool large so wages stay low, but it is at odds with the social goal.
You're not giving them anywhere near enough credit if you think a super simple strategy of pandering to the uninformed bundled with restricting education is somehow "5D chess".
Don't be fooled by all the mouth breathers they trot out to preach their dogma, they're the rodeo clowns designed to distract you from the matador stabbing us with spears.
I won't say it's all cohesive, or that within their ranks there isn't dissection and in-fighting... but anti-education and pro-righteousness is the baseline that they all follow.
Boeing enters the chat. I'm aware its not a 1-to-1 analogy, but union busting, deregulation, and generally just shitting on education so voters vote against their own self interest I would guess has caused planes to fall out of the sky...
