well...
to say porn is bad is just silly.
but then there is always a good time for things and a bad time for things.
To put it bluntly humans need a release something to focuse there energy on, if you don't get them one the presher will build till it eventuly exploads, and no exploshen I have ever seen was good.
Porn provides a 'safe' way to release some of that persher.
you take that away and you are going to cuase problems ferther down the line.

though, I must admit I am also far to lazy to read the entirty of your post, I got the genral idea.
Porn is nether good nor bad, but nether can you say it's not harmful. porn in the wrong hands can be harmful, like the 8 year old who has no clue what sex is. Should Porn be controled? to a exsent yes. it is the job and obligation of the parents to moniter there own children no the manufactuer of the porn it's self.
To just say that it's the job of the people who make the porn to make sure minors don't get there hands on it is ludricus. sure they 'could' make it harder to get but a lot I would say a good 50% of porn sells is done anominisly. though every american has seen and used porn at some point in there life (if they say otherwise they are ether liers or in needs of a shrink) not all will 'admit' to having seen or used porn. So makeing porn harder to get would efectivly kill the busness.
Not to mention the porn makers can't watch your children as closely as you do. I mean you live with the child (hopfully) they don't.
To sum up my rather long post.
Your the Adult, do what you think is write conserning this mater.
