“Lived a hero and died a hero,” York University student Somar Abuaziza wrote on Instagram following the death of Hamas leader Yahya Sinwar last October.

Last Tuesday, Abuaziza became president of the York Federation of Students (YFS), representing nearly 50,000 undergraduates and boasting an almost $2 million annual budget, raising concerns from students and others who question the leadership of a student leader with views they see as toxic.
