there would be no hell to pay because you have no rights.
The Courts removed parental rights of children sent to government schools a long time ago. they control your children when they are in your care, you have nothing.
Most parents do not realize this.
I had a (very conservative) relative get angry when I pointed that out. He didn’t believe me and said it wouldn’t be the case with his kids. They homeschool them through sixth grade then send them to public school for the remaining years.
The parents who do realize the danger of “in locus parentis” in increasingly godless public schools tend to homeschool their children.
