#onthisday, December 6, 1989, a man named Marc Lépine entered a mechanical engineering classroom at Montreal's École Polytechnique armed with a semi-automatic weapon. After separating the women from the men, he opened fire on the women while screaming, "You are all feminists," he then turned the gun on himself; fourteen young women were murdered. In his suicide note, Lépine blamed feminists for ruining his life. This event became known as the École Polytechnique Massacre, a moment in history that became a symbol and a call to end violence against women.
