Free speech on college campuses has become a topic of impassioned debate, as the lines between hate speech and harassment, or peaceful protest and public disturbance, are rather blurry and hotly contested. Particularly since the protest movements of the 1960s, college campuses have long been a kind of testing ground for different norms and boundaries of free expression. At the same time, some institutions of higher learning have speech codes which many feel are serving to silence debate and discussion among students in the name of protecting feelings.   Our guest this week, Wendy Kaminer, is among those who believe that things like speech codes and trigger warnings have gotten out of control. Kaminer is a lawyer and writer who has dedicated much of her life’s work to defending free speech. She and host Lindsay Beyerstein engage in a spirited discussion about the grayest areas concerning speech and censorship on campus and in the culture at large. Kaminer will also be one of the many fantastic speakers at the fourth Women in Secularism conference, September 23-25 in Alexandria, Virgina.
