You certainly won’t see this in the Mainstream Media. Nakba Day is on May 15th each year; it is the day Palestinians remember the “catastrophe” of the founding of the state of Israel. It is also the day when strictly Orthodox Jews demonstrate in solidarity with Palestinians against Zionism.
The London demonstration was small. London has only a small population of Haredi, or Ultra Orthodox, Jews. The biggest demonstrations happen in New York, which has by far the largest Orthodox Jewish population outside of Israel. There were, of course, Haredi Anti-Zionist protests in Jerusalem:
The main banners in Hebrew say: “We mourn 71 Years of Zionist Rebellion Against the Almighty and His Torah”.
Orthodox Jews believe they “are in exile by Divine Decree and may emerge from exile solely via Divine Redemption. All human efforts to alter a metaphysical reality are doomed to end in failure and bloodshed.” They are deeply opposed, to put it mildly, to the entire Zionist project. More information about them can readily be found on their websites, such as Torah Jews here, International Jewish Anti-Zionist Network here, or Neturei Karta here. To say such information can be readily found is perhaps an exaggeration; as with all things, you have to know it exists to even start to look for it. The Mainstream Media will only ever tell you that the State of Israel represents Judaism. They also mostly concur with the Zionist view that Anti-Zionism is identical with Anti-Semitism. According to that definition, there are huge numbers of Anti-Semitic Jews. And the Anti-Semitic ones happen to be the ones who take the Torah, the Jewish Scriptures, most seriously.
