Thank you dang; here's the thing, even the most charitable reading of GPs comment indicates that he feels being unable to restrict a child's right of access to their parent is unfair in some way.
No matter what you may think of parents, it is absolutely horrific that someone will argue for restricting the rights of children, and do it in a way that he feels is acceptable in society (custody is only in small part about having access to one's children; the actual right is to the child, not the parent - the child has the right to access to their parent).
I wanted to make him understand that trampling over children's rights is not acceptable.
