That may be true, but way more kids get sent to school then are home schooled, so that doesn't mean much on its own.
The issue is that when a kid's at school, there are many people who may notice something's wrong. From teachers, school nurses, school administrators, and even other kids. This is by no means perfect, and many, many cases of abuse slip through the cracks. But it is something, which is more then many home schooled kids have.
While I'd wager most home schooled kids aren't abused, the fact of the matter is it's much easier for an abusive parent to cover up their abuse if their child is home schooled. You may still feel home schooling is a net positive, but this aspect is very hard to deny.
