Yes, exactly. Censorship is censorship.
Child porn is illegal because its creation damages the child. Its continued distribution is not the primary problem, the fact that it was created in the first place is. So the solution to child porn is to find it, use good-old-fashioned police work to find who made it, and use the legal system to remove that person's access to children.
No need to break the Internet and restrict free speech for this very-special case. Let's spend the money we want to spend on censoring the Internet on more detectives, so that child abuse can be eliminated!
The same goes for "counterfeit goods" or whatever the DHS used as rationale for seizing domain names. Don't break the Internet; just buy one of the fake watches, ask UPS where it was shipped from, get a warrant, and bust the guys! Right?
(I fear that in the US, though, the problem with child porn is not that children were abused, but that people like something in a sexual way. Consider the person who was mailed a box of comic books that depicted "under-age" children in a sexual context. The government wanted to put him in prison for 15 years. For receiving a box of books.
"Sexting" is another example. It's doubtful that one can abuse one's self, but the government still wants to put people in prison for it.
What I find most amusing is that all people look pretty much alike when naked. I don't understand why naked pictures are such a hot-button political issue. It seems like the government just doesn't really want any depictions of sex [children, adults, tentacles, or otherwise] around at all.
But I digress.)
