1) The referendum that the protesters are requesting was already held a few years ago. Labor candidate Amram Mitzna ran on a platform calling for unilateral withdrawal, while the Likud candidate Sharon dissed such an idea. The Likud won almost twice as many seats as the Labor Party.
2) I hold that the destruction of Jewish settlements in the Land of Israel is against Jewish Law. Even if 99% of the public supported such an action, I will not support it and will do nothing to implement it. If the laws of men conflict with the laws of G-d, my loyalty will always be with G-d.
3) Demonstrations are a tool in a democracy. Since the present Prime Minister has disdained his own party's platform and two internal party elections which rejected his disengagement plan, he has become a dictator. Democratic tools do not work with dictators.
So instead of wasting my time hearing the same banal speeches that are repeated ad nauseam at demonstrations of this kind, I attended my daf yomi class as usually and learned another page of Talmud. This is my contribution to the People of Israel and the Land of Israel.
