"Under its adapted guidelines, a Labour Party member is free to claim Israel's existence is a racist endeavour and compare Israeli policies to those of Nazi Germany, unless "intent" – whatever that means – can be proved. "Dirty Jew" is wrong, "Zionist bitch" fair game? In so doing, Labour makes a distinction between racial anti-Semitism targeting Jews (unacceptable) and political anti-Semitism targeting Israel (acceptable)."
