I think it impossible to gain the perspective of a parent until you are one.
SC -- you have some good points, but you seem to be coming from a parentED perspective rather than a parentING one. The only thing you said that stressed me out a little was the comment that sort of thought it was "human" for my ten year old to watch porn, and it was no big deal. It was a huge deal.
Luckily, we're all through it. I have asked him numerous times if he wants a magazine, and he just wants to put it all out of the picture. We put stuff on his computer that make it impossible to go there...he in fact wanted that! He found the entire thing stressful, but he also remained compelled - which I guess speaks to the strictness (which I am not). He WANTED restrictions and guidelines to help him.
