I'm a product of "alternative" education (my public middle school was middle school + high school, my undergrad had more grad students than undergrad, my grad school had more postdocs than grad students and no undergrads). My college was popular among children who had been homeschooled, and after college my social circles seemed to have a lot of kids who were homeschooled (for religious and non-religious reasons), and I have to wholly 100% agree with this. I don't understand why people think that socialization in the form of public schools - which is actually quite artificial and 'unnatural' in terms of human history - is necessary or desirable.
