In a lecture on September 15 Jong insulted the victims of sexual slavery for the Imperial Japanese Army and participants in the independence movement and shielded pro-Japanese lackeys, claiming that victims of sexual slavery were not slaves and that all Koreans were pro-Japanese ones in the period of the Japanese imperialists' rule.

The students demanded the university side dismiss Jong An Gi for his pro-Japanese remarks.

They also urged Jong to make an open apology to the victims of sexual slavery and the descendants of the participants of the independence movement.
