In Ank Morpork, and in most cities that pretend they are not Ank Morpork, authoritarianism does not stride in wearing a black cloak, it shuffles in behind a health and safety leaflet and a funding form? What I like about Fall of Freedom is that it treats censorship as something practical to be tripped up, not a distant cloud to be moaned about, so you get workshops on banned books, gigs raising money for civil liberties groups, and a few excellent posters into the bargain. What worries me is our species’ remarkable ability to treat even the most urgent warning as a limited series, binge it for a weekend and then move on to the next crisis. Stories only change the world when they are told again and again by people who are prepared to be annoying about it at parties. If these six hundred events turn into habits, local networks, shared legal funds and a touch more courage in every programming meeting, then the joke will be on the would be censors. If not, the city will carry on much as before, only with nicer commemorative tote bags.
