Note that I carefully did not say anything about what abuse is. Unfortunately there is no agreement and I don't want to get into that debate (it is well worth having, but it would change the direction I'm trying to go here).
Homeschooling is debatable, if the children are evaluated to be equal to their regular schooled peers, I don't think the child should be taken out of the family environment, but should be subject to further wellness checks by social workers.
A challenge is where the ripped-off children wind up, a foster home system with it's own abuse issues.
