I heard this “but we have homeschool play groups! It’s different!” in the 2000s from every single one of the parents for whom homeschool was a disaster. It’s funny hearing it fresh here.
To be fair though, I'd imagine an hour or two a week of socialization is still quite insufficient. On the flip side, 10+ hours a day of socialization is unquestionably unnecessary, and forcing your kids to become conformists or get beat up/bullied/etc (which is the reality in public schools unless you live in a really rich neighborhood) in order to get a little more socialization time isn't a good tradeoff. There are a lot of non-school activities children can engage in to get peer socialization where the type of bullshit that occurs in public school doesn't fly, due to the adults that run those activities losing customers and having their livelihood threatened if they let kids be little cunts, unlike public schools.
So I heard the same refrain from you that I heard from my parents and their peers, decades later from someone I don’t know, and your takeaway is that we must be in very different circumstances? Bud, you’re almost certainly reusing the same homeschooling materials and curriculum help my own parents did.
