East Jerusalem is not considered "disputed". It has been annexed by Israel and this is considered illegal by anny definition. No one except Israel accepts the fact that it is not occupying land. Evenif it were correctly defined as "disputed", the occupying power has no right to change the demographic reality of the area occupied nor does it have the right to take lannd by confiscation, annexation or expropriation. To use the term "judenrein" is a vulgarisation of its true meanning which refers to the Nazi regime annd should be reserved for that period of time. Arabs in Galil were there prior to zionist settlement. Jews on stolen land in the West Bank came there to take control and have set up one system of law for Jews, another for Arabs. Extermination of Jews is another hysterical misuse of the term. The groups you mentioned are out to destroy a zionist Israel, not all Jews worldwide. Ethnic cleansing is something zionism has done, as is well documented in history.
