As colleges across the country, from Harvard to University of Mississippi, continue to witness racism on campus, we look at a new film that tackles the issue through comedy and satire. “Dear White People” follows a group of black students at a fictional, predominantly white, Ivy League school. One of the main characters, Sam, hosts the campus radio show “Dear White People,” where she confronts the racist stereotypes and dilemmas faced by students of color. Racial tensions on campus come to a head when a group of mostly white students throw an African-American-themed party, wearing blackface and using watermelons and fake guns as props. We speak to actor Marque Richardson and award-winning, first-time director Justin Simien.
