It is not an accident that the three key planks of the Left-wing outlook today – the anti-Israel anti-war sentiment, the shallow anti-capitalism of Occupy, and the worship of those who leak info from within the citadels of power – should all have had issues with anti-Semitism. It is because the left, feeling isolated from the public and bereft of any serious means for understanding modern political and economic affairs, has bought into a super-simplistic, black-and-white, borderline David Icke view of the world as a place overrun and ruled by cabals and cults and sinister lobby groups. And who has always, without fail, been the final cabal, the last cult, to find themselves shouldering the ultimate blame for the warped, hidden workings of politics, the economy and foreign turmoil? You got it – the Jews.
That parts of the left has a penchant for anti-semitism, and other forms of mad conspiracy-mongering, is not a new observation. Take this link, for example, from Discoverthenetworks.org
