This column will be boring to read. You know I try. I really do, but there is no other way. This week I write about antisemitism. There is so much of it about, and so much is said about it, that by now, you must as be bored with it as I am. But it is because there is so much of it that we must rouse our interest yet again. I’ll be quick. I don’t wish to bore you, but it’s interesting.

Some people say we are witnessing the New Antisemitism, an infusion of Islamist zeal into the radical Left. The alignment suggests a certain novelty, but I must report that the New Antisemitism is pretty much like the Old, only with extra diversity, which is the conformity of our age. If the New Antisemitism feels new, it is because, since 1945, it was considered vulgar, at least in the Western liberal societies, to say that Jews are poisoning the wells, rigging the financial system, and sacrificing children, so they must be purged from society.
