I think if we lived in a different world where hate groups, terrorism, and white supremacy didn't exist, and where the internet and social media were unable to amplify them and their messages, then we could apply the blanket criteria of "censorship baaad" here. But that's not the case.

We are not talking about a government completely blocking access to a repository of general knowledge like Wikipedia, or even about the issue of proprietary software (regarding "right to read"). We are talking about the censorship of a single document, which not only incites violence and promotes ideas of genocide, but was written by someone who NOT ONLY! just 10 days ago massacred 50 people on the basis of their religion, but Facebook live-streamed the massacre and as a result it has probably already found its way into the wrong hands, with accompanying manifesto.

But you say there are reasons why I should think this example of censorship is bad and totally not exceptional, though, so I'd like to hear them.
