It's simple. Rural parents and older people have been convinced over time via propaganda that "the school system" is why younger people don't generally share their values and ideology. This can be used in all kinds of ways to create emotional responses later.
For example, many conservatives in the western states are convinced young arsonists are burning down forests and fields because they are homeless and feel entitled to housing. Of course, there is no proof of this, and they don't think it can be climate change because they don't think climate change is real.
As a result of all this, they are very willing to take their kids out of school and switch to some homeschooling program so they don't raise homeless arsonists.
I wish I was kidding.
That's how you know they're paying attention!
