I don’t disagree with your final statement, but they’re also not wrong.
Growing up it was well-known that homeschool kids were strange, intelligent in some ways, and completely inept in most ways that mattered.
People who desire to completely shield their children are just as detrimental to their children’s development as those who over-expose. However, in my purely anecdotal experience, the ones who were over-exposed were better off than the former.
And the middle road led to better outcomes overall.
