How can people be dumb enough to believe the Labour Party is anti-semitic?

It is an example of "if you repeat a lie often enough it becomes the truth" in action. The Tory-supporting Zionist leaders of the main Jewish organisations, with the help of the right-wing press, have been portraying Labour's criticism of the Israeli government's treatment of the Palestinians as "anti-semitic" for a long time now. Only a small minority of Labour members have been guilty of real anti-semitism, things like Holocaust denial.
