Not really the right thread, but I think this needs an answer.
NZ has - as any other country - some rotten apples in their (our) society and (again as everybody else) a somewhat incompetent system to protect children ... and yes, our justice system is far from perfect (though I haven't yet seen the perfect one). I don't argue that - and if you want to discuss that, just create a thread. I assume however there will be little disagreement.
China on the other hand is systematically abusing the human rights of anybody getting into the way of their system and government. They are quite happy to incarcerate and if it is more convenient to kill their opponents.
And I am sure, they have neglected children as well in China ...
Surely - you must be able to see the difference?
