If it's really that difficult for parents to engage their children and parent them, maybe that says more about a society that doesn't prepare parents for parenthood than it does about those who don't have children.

There is no "good parenting" fix that will keep children from trying to access inappropriate content, forums where unhealthy conversation takes place, pornography, and worse. Being a good parent does not and cannot remove the curiosity, temptation, and ability to access bad content. This is a problem with the human condition, not bad parenting.

As a parent myself (and, I hope, a good one), I have found it very difficult to effectively monitor and limit my children's ability to access these things. And I have more facility with technology than the average parent. It's a complex and frustrating problem and the stakes are high.
