Easy, tiger. Vuvuzelas were not invented for the World Cup. As for your assertion that this is general attack on noise-makers at matches, well I haven't heard much of anything bar contumely directed specifically at vuvuzelas. Making noises with mechanical gizmos at matches is time-honoured. When I was a little lad 50 years ago watching Bury FC from the terraces there a bloke banging a bass drum all through the match behind me and a bunch of blokes with wooden football rattles a foot long in front. Beware the stench of imperialism!
