Greatest. Assuming this happened, was it one or two or five people who insisted on doing such a terrible thing to advance their personal agenda, or was it articulated, legislated, and implemented policy of the state? That is the difference between individual wrongdoing and what you and your supporters call a “shmad”.
If you are making a blanket accusation about the state of Israel or the Zionist movement, at the time you are discussing they had institutions, including the Jewish agency and the knesset, and those institutions have ample documentary evidence of everything they did during that period. There are records of pretty much everything that was decided and done by the government and its institutions. Even secret things, and many authors have taken advantage of the access they have to records of policies, actions, courtcases, guidelines and laws to criticize the State for any number of things. I’m not asking you to reinvent the wheel. I’m telling you that if it happened, and it was policy, the evidence is in documentary form, so back up your assertions with facts.
