Antisemitism Mutates

“Antisemitism is not a unitary phenomenon, a coherent belief or ideology. Jews have been hated because they were rich and because they were poor; because they were capitalists and because they were communists; because they believed in tradition and because they were rootless cosmopolitans; because they kept to themselves and because they penetrated everywhere. Antisemitism is not a belief but a virus. The human body has an immensely sophisticated immune system which develops defences against viruses. It is penetrated, however, because viruses mutate. Antisemitism mutates.”
