Not just a Bronze Age ideology steeped in violence but usually a version of that which is chock full of whacky conspiracies like evolution being a lie by the devil, the earth being only 6000 years old, plain weird things like Adam and Eve riding dinosaurs (or alternatively dinosaurs being a lie planted by the devil), that abortion is a silent genocide of trillions of humans, and just all kinds of other horrifying, anti-social, child abuse shit. Manipulative and abusive psychology has been perfected by these people who publish many of those courses to coerce, manipulate and control kids into their cult. To teach them natural urges like masturbation, sex, etc are wrong, evil, etc. So they grow up hating themselves, seeing themselves as fallen, evil, wicked with a limited range of expression, stunted growth in many realms, etc.

So yeah, home schooling minus that will definitely turn out a much more normal, well-adjusted kid.
