There is no arguing with you people. The sort of things you miss out on if you're homeschooled are totally unimaginable to you so there isn't anything I can say that will change your stance unless you literally live through the experience. It has nothing to do with only comparing yourself to the median or upper quintile of public school socializers. The only way that position would seem reasonable to you is if you never met any homeschoolers or only talked to the parents, who obviously will be extremely hesitant to admit to mistakes because it makes them look bad.

There's also a huge and obvious problem with studying homeschooling. Part of the disadvantage is that each homeschool environment will be radically different because it's impossible to control for what a given home life is, the type of parent that would homeschool their child, and the sort of education they otherwise would have had if they weren't homeschooled. It's also really easy to track down all the homeschoolers that ended up going to college because that data is already gathered. It's a lot harder to track down all the homeschoolers that never left their parents basement or work the night shift at the 7/11 because they barely learned how to read, so you really can't say that "statistically" it's better or worse. Of course the data will be skewed so homeschoolers seem like higher performers.
