When Walter Wolfgang uttered his one-word intervention into UK Foreign minister Jack Straw's speech to the British Labour party, he exercised his right to freedom of speech and dissent. But in his wildest dreams he could not have calculated its effect.
Fortunately for him, and for us, the British Labour Party has reached that moment in its process, as did the Tories under the appalling Thatcher, when it believes itself to be above the law, above criticism, above the people.
Fortunately they picked on a very eloquent, very hard-assed Jewish, Holocaust Survivor. If you wanted your worst nightmare as a witness against fascism, Walter Wolfgang has to be the man, and he lives in a world where his single word, and the thuggish response to it has echoed smartly around the world.
