If folks like me say that Jeremy Corbyn's Labour party is so infected with the virus of anti-semitism that it has become institutionalised I am accused - as an out and proud right winger but also as a proud Zionist - of smearing. The video below is remarkable in that it is produced by and features a raft of fully paid up Guardian reading, left wing academics, many indeed are Labour Party members. It is a truly shocking expose of the evil at the heart of the British left.
