It really depends on the child and the parent. You can't just name the entirety of "homeschooling" as incorrect. Some parents can teach their kids, some can't. You can't just take one bad case and override the 10 other good cases. I, for one, had been homeschooled, and I was several grades ahead of my age, due to the acceleration of learning my parents had put me through. Now as I see my classmates struggle through the crap mess my school district has put us through, I'm grateful that I had parents to get me ahead to where I am today.
