I think quality over quantity matters. There was no one at my academic level at the public school, but two lived at my house. If you're worried about social skills, why do you expect an open admissions school to be able to train your children better than a more curated social group? You could say, "I don't trust parents to actually give their children experiences that would be beneficial, because maybe the parents are bigots or something," which like, sure is true. Lots of parents are like that. But they already pretty much have free reign to put their child in the local Bible Bootcamp instead of the public high school, so you're not really preventing this bad thing from happening, but you are preventing a lot of parents who would give their children a better experience than the local vaudeville show.
