Racism is not a specific illness but a general sickness. Display one symptom and you display them all. If you show me an anti-Muslim bigot, I will be able to guess his or her views on the European Union, welfare state, crime and “political correctness”. Show me a leftwing or Islamist antisemite and, once again, he will carry a suitcase full of prejudices, which have nothing to do with Jews, but somehow have everything to do with Jews.
The Labour party does not have a “problem with antisemitism” it can isolate and treat, like a patient asking a doctor for a course of antibiotics. The party and much of the wider liberal-left have a chronic condition.
As I have written about the darkness on the left before, I am not going to crow now that it has turned darker than even I predicted. (There is not much to crow about, after all.) I have nothing but respect for the Labour MPs who are trying to stop their party becoming a playpen for fanatics and cranks. It just appears to me that they face interlocking difficulties that are close to insoluble.
They must first pay the political price of confronting supporters from immigrant communities, which Labour MPs from all wings of the party have failed to do for decades. It may be high. While Ken Livingstone was forcing startled historians to explain that Adolf Hitler was not a Zionist, I was in Naz Shah’s Bradford. A politician who wants to win there cannot afford to be reasonable, I discovered. He or she cannot deplore the Israeli occupation of the West Bank and say that the Israelis and Palestinians should have their own states. They have to engage in extremist rhetoric of the “sweep all the Jews out” variety or risk their opponents denouncing them as “Zionists”.
