It seems that the problem in this case is not the homeschooling, but the parents. It's certainly true that neither homeschooling nor public schooling would be able to prevent a parent abusing their child. Perhaps the next step should be "public parenting", if parents can't be trusted to act in the best interests of the child...but we already have this (social services, foster care), and I suspect a much higher proportion of publicly schooled children end up in foster care than homeschooled children. However, I've never seen any research data on that. If you don't mind talking about it, roughly what proportion of the kids you interacted with in the foster system had been homeschooled?
