Re: @Binraider - There's no "right sort of censorship"
If I was to post something that is libellous, and it was removed, would that be censorship?
In what sense would it be a valid debate to discuss whether or not there is veracity in such a claim as, for instance, "Annoymous Coward has sex with dogs"?
There is a clear line between removal of false or defamatory claims, and censorship of legitimate debate. To claim otherwise is to draw a false equivalence and is deeply disingenuous.
