In the rural areas that I've lived in, it's mostly about a strong desire to supplant science and history with religious ideas and principles.

I hear this a lot, and it may be true, but I am very skeptical that it matters. The statistics about home-schooled children don't support the idea that they have horribly inaccurate models of the world guided mostly by religious thinking. Or if they do it doesn't seem to affect life achievement in any important way. Instead home-schooled children are typically more advanced at graduation and have higher lifetime achievement metrics than their public school counterparts.

As an athiest, and a bayesian, it's difficult for me to worry about other peoples religious beliefs that don't seem to negatively affect them or me. Especially when there is propaganda taught in the public schools that does warp the students' world views in ways that harms them and me.

That has been the case for a long time, and I guess something about the current generation of parents has gotten them to act more on it. My dad came from a very religious family and they all did private religious schools for their early grade school years. Then they went to public for high school years.

If I had to guess, its maybe something about the demise of church life that has gotten religious parents to just pull back entirely. It wasn't that uncommon for public schools to make nods toward Christian ideals/lifestyles before like the 90s, but now that stuff just doesn't happen anymore.

I won't pretend to know where you live or what those people's desires are but I definitely started homeschooling after the last US administration took moral volatility to new standards. The principles taught in schools just did not align anymore with what was common sense when I was in school and what I believe in. Now before you judge, I'm not looking for a fight. My wife and I have both master-degree educations in CS and law and our four kids have been to public school in the US and abroad, they've been to an evangelical christian school, and now that we've decided to homeschool for two years, we're not likely to take them back. The traditional school aspects take up 2-3h per day at most, then comes the school of life: raising and caring for animals and plants, fixing the truck or other engineersy activities and of course plenty of fun activities outside of the too-busy-to-be-fun times. My kids have learned of historic events such as Jamestown, Gettysburg or Mount St. Helens at the actual site of the event, they've been to most of the national parks and the fear of being socially-disconnected is not more than a fear before you start. Heck, thanks to Starlink they can even talk to their friends while we're driving through a desert.

Now let me also say that preparing the curriculum, ordering the materials etc. takes a lot of effort and discipline. It's definitely almost a full time job and I'm blessed with an amazing wife that's gifted in all that but the reward is more than worth it. Also, if you're thinking about it, many states have home school support programs and put you in touch with other home schoolers in the area.

That is exactly what I've seen, to keep kids in their brainwashing bubble.
