Responding to hate speech is difficult because its definition remains unclear. However, the reiterated theme throughout the University of Delaware's conference on free speech was the importance of positive communication. The title of the fourth session was “Are more laws necessary for responding to hate speech?” The guest speaker was Sara Wachter-Boettcher, author of Technically Wrong: Sexist Apps, Biased Algorithms, and Other Threats of Toxic Tech.

UD's Communication Department hosted "Speech Limits in Public Life: At the Intersection of Free Speech and Hate" on March 14 to 15, 2019. Legal experts and free speech scholars from around the country discussed how to define hate speech and respond to it both digitally and on college campuses.
