From Nick Cohen's essay, "Bound and Gagged":
The grand posture of writers in liberal democracies is that they are the moral equivalents of dissidents in repressive regimes. Loud-mouthed newspaper columnists claim to 'speak truth to power'. Novelists, artists, playwrights and comedians announce their willingness to transgress boundaries. Their publishers look for controversy like boozers look for brawls because they know that few marketing strategies beat the claim that a courageous iconoclast is challenging establishments and shattering taboos.
To maintain the illusion that they are part of some kind of radical underground, intellectuals must practise a deceit. They can never admit to their audience that fear of violent reprisals, ostracism or crippling financial penalties keeps them away from subjects that ought to concern them - and their fellow citizens.
