Members of Students for Justice in Palestine attending a multicultural event at the University of Ontario Institute of Technology intentionally covered up the sole Israeli flag with an Algerian one.
When they went to their Facebook page to brag about the incident, they allegedly referred to Israeli Jews as “rodents”. Describing Jews as vermin was a mainstay of Nazi propaganda, which frequently depicted Jews as rodents. According to the International Definition of Antisemitism, “using the symbols and images associated with classic antisemitism (e.g. claims of Jews killing Jesus or blood libel) to characterise Israel or Israelis” is antisemitic.
A Jewish student was then told to “go back to Palestine”. Given that these people are actively campaigning against Israel, telling a Jew to “go back to Palestine” seems bizarre, but it is antisemitic nonetheless.
