You have to be kidding? You're spouting that NEA nonsense!
I and other FR homeschoolers have engaged with gondram, and others like him, on this point many times. The usual response from people holding down this position generally ends up being “Well, I see you’re qualified, but my cousin-in-law Egbert and his wife are morons and they’re homeschooling so most homeschool parents must be like that”.
Personally I think homeschooling is more important, if anything, in high school, because that’s when the peper pressure really kicks in.
In your opinion, what percentage of American adults are qualified to teach algebra, geometry, trig and calc? Feel free to break it down into 4 subsets if you like.
