This was a protest celebrating the acquittal of some anti-Zionist leaders in Argentina. They were charged with hate crimes.
It occurred in 2010, but it shows the increasing anti-Zionism in South America from the left.
What is interesting is that the Jewish community could persuade the government to lodge charges.
Argentina has a large Jewish Community. It is shrinking, but it has clout. That being said, the leaders were acquitted.
