Are you suggesting there's no mean behavior on 4chan?
I find 4 chan to be an interesting experiment. Yes it mostly is a cesspool. Yes folks there are pretty much awful. But it's also extremely egalitarian. Everyone is on the same, whether you be an old * or a new *. I don't partake but I like to dive in and observe them. Fascinating, because as much as we'd like to deny it, 4chan is the whole spectrum of humanity.
Personally I think all content should be unfiltered and the people who cannot handle this, should learn it. Open discussion is difficult when you have to self-censor all the time. We have it so bad, there's even a bunch of words we're forbidden from using in filtered communities and it's sold as a good thing. Lots of ideas and opinions are also banned, which is really unfortunate. We tend to criticize China for exactly the same things that are completely normal for most of us. It's just that China bans different ideas.
