The problem is not pornography neither real paedophiles, the problem is art, they want to destroy art one more time in history.
The only one that goes to jais is the guy that has some images in his hard-disk. Nothing happens with bishops, pastors and politicians no matter how much are involved with real paedophilia, they are protected and untouched. The very few street paedophiles that are identified and located are sent to psychiatric institutions. No jail for real paedophiles!
As for real porn, it remain untouched. Porn is the #1 business of internet, it generates tens of billions profit, is a big $$$$$$$ and all banks, credit card companies, politicians, moralists, religious participate of this profit.
All the measures, action and laws are against artistic expression, no matter if the art is good or a crap, is art. Sites dealing with art are banned, blocked, closed, under strict censorship.
You don't see any real porn site closed, any kid can see any real porn in the internet  he wants, the thing that a kid cannot see are nude Aikos at Renderosity, or faeries that are not fully dressed!
A kid can watch a porn DVD, but he is not allowed to see a nude statue in a museum.

This is the first step for banning art, porn and paedophilia are the tools used. With underage argument you are removing a segment of artistic expression and with the porn argument they are resticting a big part of artisring expression.
If successful this first stage the second stage will be banning all nudity from art and what is nude is also expandable, if a woman is dressed with a burka, she's nude!
The third stahe is suppress all human reprsentation, neither a clothed man is saved, they have another tool for this task.
"Your image was removed from the gallery and you are banned from the site because the man in your picture looks as a gay"!
As 90% of western art deals with humans, wetern art will be reduced almost to nothing.

You can think that I am exagerating, that is fantasy, but look in history what happened with art in Germany after the Reform.
It can happen again, but it doesn't mean that it will happen, it only depend on what we do. If we do nothing it will happen, but if we not remain as stupid sheep they can do nothing and the world is too big to be controlled by a bunch of fanatics.

Stupidity also evolves!
