Anecdotally, those around me that are homeschooling are doing it for one of two reasons:
1) Right-wing disgust over woke issues.
2) Fear of school shootings.
That's coming from a non-tech middle/lower-middle class setting. 20-30 years ago, when I was in school, most of the homeschoolers seemed (again anecdotally) to be based on religion or some other idiosyncratic reasoning rather than the reasons I cited above.
I have some friends who are Christian but left wing (their kids would come over to play and draw pictures about helping poor people.) The dad teaches CS at a small Catholic college, mom stayed home and educated their kids.
The "disgust over woke issues" existed in some form 30 years ago when people were homeschooling but it had not hardened into the constellation it is in now. Back then you could get folks like that to talk articulately about how they disagreed with secular values, introduce a word like "woke" and now people talk past each other, at best, if they talk at all.
I miss the days when young earth fundamentalist Christianity tinged with racism was my most compelling ideological opponent.
Personally I see it as bad theology as much or more so than bad science.
I mean, how do you reconcile the idea that "God is great" (Muslim slogan but how you can not believe that as a theist?) with the idea that the world is just 6000 years old and he sits on the throne and is obsessed with Jewish people as opposed to the scientific picture that the world is at least 13 billion years old, 'his image' is inscribed into the molecular structure of our cells, which implies God is a lot bigger than that.
> 2) Fear of school shootings.
I would add:
3) Fear of fear of school shootings.
The active shooter drills and other security measures that American kids go through in some schools are positively dystopian. Even if the chances of a school shooting are statistically very low, the measures put in place to prevent them are probably not good for kids' psychological well being.
