Haha, I've never heard that before. I personally don't think socialization at public school has much to recommend it, but lots of people also have fond memories of their time in school, so I haven't found it productive to get really negative on it.

I mostly just want to remove socialization as the deciding factor that makes parents keep their kids in school when they'd really rather do something else, because, as you say, socialization in public school very much has a downside, and I think at best, it's a wash compared to homeschool.
