And demanding that people do live by those anarchic rules because 'it's the Intenet' is any less Orwellian in nature? It's still demanding people live to rulesets they don't want to.
Thing is, take something like 'The Modest Proposal', that got famous as free-speech because it flew in the face of what everyone believed was 'proper' behaviour. At no-point did there arise a group that actually agreed that poor people should be used as food, it was the universal disgust at the concept that caused the fame.
The problem with things like social extremism is that there is no unit of it., what is defined as 'normal' society would be considered extreme by a Victorian or a Puritan, it's all down to perception. There is, however, an attitude on the Internet that anything goes, and any voice that tries to get people to behave in a more tolerant manner towards each other is silenced as being 'against Free Speech', which is an irony that shouldn't be lost on anyone.
