@paulfree14 neo-nazis are indeed a threat to free speech. They may claim that they like it, but when they show up on the street they're more interested in getting into a brawl or calling for people to be killed or deported.

Neo-nazis and their totalitarian ambitions are only one of the threats to free speech in the foreseeable future. The bigger threat as I see it is from pervasive corporate surveillance combined with government data retention. My guess is that schemes like "prevent" in the UK will grow to include a wider range of political speech as the predicament of capitalism gets ever more precarious and the remaining neoliberals seek to stabilize business as usual by rooting out the more obvious critics of a system which benefits fewer and fewer.
