First sentence. How did any of them know whether there were any Jews at all in the crowd? They were ostensibly protesting zionism, led by a known rabid zionist.
I have addressed the actual content of the chants as far as I could find any. You should now link to your accusations of shouts of "Jew Jew Jew". I have not seen them. Note that I also previously said I didn't doubt that there were some individuals, as always, but I want to see where the crowd was chanting that collectively for your point to be valid.
