Parent-child relationships are more about mentoring and guidance than control. Pure force is almost never an adequate answer to any problems that a child experiences. How on earth can you force someone to study without fundamentally harming him, if he has a bunch of underlying problems that effectively prevent him from learning? No way, it's just a lazy approach and unwillingness to figure out the real problem. Also, there are many things, that you can teach only through personal example and overall context inside a family. Bad websites? If you are spending enough time with your child, teaching by example, family culture and discussion, explaining what is right and wrong, he is very unlikely to develop any interest towards "bad websites". Besides, the idea of blocking all possible sources of negative content is pretty laughable from a certain kid's age. As for the religion example, I have no idea why one should want to teach children any religion apart from maybe some historical and cultural perspective.
