Guy Oberlander, president of the university’s Jewish Society, tweeted from the conference hall that he “had absolutely no idea" about the motion until he saw the schedule for the SU's AGM.
“Don’t let outside affairs affect the safety and welfare of my friends and family. I am sat here at the moment already nervous,” he said.
A second Jewish student pleaded with those at the AGM, tweeting: “Don’t vote for this antisemitic mess of a motion".
A third tweeted she was “very relieved" and could "sleep easier tonight”, while another wrote: “Thank f**k the motion was voted down. Blatantly targeted and biased, with seemingly no support from Jewish students.”
Daniel Kosky, campaigns organiser at the Union of Jewish Students (UJS), told the JC the motion was "divisive", adding it “seemed to define antisemitism for Jewish students, without any consultation with them".
He added: "It played merely lip service to antisemitism and was a blatant attempt to ‘Kosher’ BDS, a movement that the vast majority of Jewish students see as an attack on their identity.
“We are very proud of Cardiff Jsoc and the Jewish students who spoke brilliantly against the motion last night, and are thankful to allies on campus who stood with us."
