Students are returning to campuses across Canada. Also returning, we can assume, will be some of the anti-Israel and anti-Jewish activism and encampments that we saw in many places last spring.

As British Columbia’s former minister of post-secondary education — and as a Jew — I witnessed the activism on our campuses last academic year veer from constructive idealism into explicit race-hatred. When we hear and see calls for violence and threats to members of identifiable groups, that ceases to be activism. That becomes a crime.
