Jeremy Corbyn was elected Chairman of the British Labour Party in September 2015. Ever since then, elected representatives of the party have expressed a steady stream of antisemitic invective, a problem that has never seemed to concern Corbyn or his associates to any great or genuine extent. Labour’s antisemitism eventually prompted public expressions of dismay from Jewish organizations, rabbis, parliamentarians, and individuals—a radical departure from the previous behavior of British Jewry, which has long preferred to keep a low profile.
