Spite and sneering

"Spiteful book reviews" are, says William Gibson, "especially common among academics who have not written books themselves" (Letters, 11 August). Presumably, those who criticise The X Factor as mindless are just jealous that they are not "living the life". In other words, that kind of generalisation is a game anyone can play. Spite is, by definition, wrong, but sneering at critics as unworthy rather than trying to listen to what they have to say reeks of narcissism.
