Question for NZPols

NZPols says:

...the question we need to ask is "what is the most effective way of changing this situation?" If attempting to change family structures is it, then we should do it. The potential returns are great enough that it warrants the "intrusion".

And if the most effective way of changing things was to force people to go to church, would you countenance that as well?

If so, then are there any limits at all to State power?
