I can't say my public school experience was great, I was bullied and didn't really click with the popular kids, but being around a cross section of actual American kids in my age group (my school district mixed middle class with lower class neighborhoods) helped me shape my worldview and learn to deal with people who didn't look or talk like me. I frequently saw fights, so I learned that you just stay away and watch…
Respectfully, A grateful dad who was homeschooled and who will homeschool.
P.S. Of course I will do some things differently than my parents, but it was an amazing gift and I had an extremely vibrant and stimulating time, including with peers (and adults!) outside of my parents' network who pushed me, challenged me, thought very differently than me, etc.
