The thing is, we are all in favor of some sort of censorship aren't we?
I want child-porn blocked. For everyone.
And you don't care what else gets blocked along with it. And you're also a hypocrite, because you said "This discussion should be had extensively and without prejudice. Without sentiments like 'will someone pleeease think of the children'.
I want sites blocked telling people actively to be violent. The whole thing is, what are exactly the limits there, how do we establish those boundaries? And enforce them?
Well, you could ban such sites, and then you'd drive your Neo-Nazis underground like Germany has. Then you can pretend you've stamped them out, like they do. Or, you know, you could let people say crazy shit on the internet so that it's easy to find the crazy people.
Outright dismissing any sort of censorship is naive.
Apologizing for any sort of censorship is naive.
