Gourmets who relish foie gras, lovers of language who think that 'chairs' are for sitting on, Christians who think that a carol service ought to have something to do with the birth of Christ and old fashioned hacks who believe that telling the truth matters more than hurting people's feelings -- almost all of us have a hobby horse we like to ride into battle against Political Correctness. And yet the PC phenomenon just seems to keep growing, touching every facet of our lives from our pleasures to our politics. Why? Could it be that this much-derided scourge of the modern world contains a germ of goodness? Edward Stourton finds examples in all walks of life -- and explodes a few myths along the way. His witty and thought-provoking manoeuvres through the pros and cons of PC are both entertaining and at times unexpectedly disturbing.
