"Political Correctness is marginal and mainstream, ridiculous and mandatory, crazy and normal."
Political correctness is the dominant ideology of the Western intellectual world. It is what the West has instead of a religion. It is a thing of the political Left in its origins and central constituency. Yet, in recent decades, it's been embraced by the mainstream political Right and Centre.
Political correctness therefore represents the triumph of the Left. Nonetheless, it very obviously violates both common sense and logic and is destructive of all that is good, beautiful and true. So, at one and the same time, PC is marginal and mainstream, ridiculous and mandatory, crazy and normal.
Political correctness obviously dominates its core territory of politics, public administration (the civil service), law, education and (especially!) the mass media. But PC also substantially shapes everything else: foreign policy, the military, policing, the economy, health services, and personal life: the mating game, friendships and even family life.
This book explains how something so bizarre and wicked could become so ubiquitous and unremarkable.
