Re: Nanny state the revenge..
But how do you enforce responsible parenting
You don't. In effect, you leave them to it and only intervene if you find they are doing (or not doing) something which will cause the child harm. It's the parent's right and responsibility to choose how to raise their child, how to protect them and educate them, and what morals to impart. It's not (or shouldn't be) their right to demand that everyone else is punished in order for them to shirk that responsibility.
