I've got mixed views. I've adult-now friends who 'grew up' on the chan sites, and are really decent people. Their views on 4chan helped me to see it all a little differently. One proposes that it's a natural foil to the increasingly oppressive and humourless atmosphere of political correctness, an outlet for 'incorrect' opinions (often simply blunt and non-sympathetic of blatant stupidity) and views. Not everyone there is like that, and certainly the truly vicious element is pretty small and owns its own corner of the site. But its tolerated, as how can they stand for freedom of speech and NOT tolerate it?
Anyway. Yes, the bullies and trolls there are pretty spectacular though. I think it's one thing to stand for freedom of speech, another thing to make it "cool" to actively cause people enormous distress and even harm.
...and of course 4chan is where Anonymous originated
