Before the panel on civil discourse begins, Andrew Perrin, a UNC associate professor of Sociology, and Elizabeth McCain, a junior history major and co-chair of Campus Y and moderator of the program, talk. The discussion is part of a series leading up to March 16. Next Tuesday's panel will be on religious pluralism. During his talk, Perrin mentioned the idea that cable TV has caused Americans to have less exposure to opposing political viewpoints save for caricatures.
