Anyone who tries to defend public education probably went to a public school.
I’ve only known two families who home schooled their children in my fairly long life. The one family, in Oregon, both kids were exceptionally bright and well mannered, and were in the Who’s Who of American Students. The other, most recent family, in California, have 3 kids, also exceptionally bright and well mannered. Their father is a school teacher so it speaks volumes about what he thinks of the educational system in California (common core?) California is near the bottom educationally, 48th I think, in the U.S.
Parents who send their children to public school are prima facie committing child abuse. No exceptions.
