“Blurred Lines” singer Robin Thicke performed at the Agganis Arena on Tuesday night, and his show was visited by protesters, as expected. A pack of people who supported a petition that asked the Boston University administration to stop Thicke from performing in a BU building took to the streets outside of the venue and made it clear that they did not appreciate his music — specifically, his lyrics. The school’s Humanist Society created the petition, and by Tuesday, it had reached almost 3,000 signatures on Change.org. “Thicke’s hit song ‘Blurred Lines’ celebrates having sex with women against their will. Lyrics such as, ‘I know you want it,’ explicitly use non-consensual language. And while watching the extremely explicit video, the insinuations grow from subtle to explicit to obnoxious,” the petition said. “Clearly, Boston University has been a bedrock for feminism and ideologies of equality more generally. It is a dishonor to our feminist history to symbolically idolize Robin Thicke by allowing him to perform his misogynist music at our university.” Tuesday night’s protesters included Derek Knox, a seminarian at Andover Newton Theological School, and Alison Landry, of Roxbury.Mark Shanahan can be reached at email@example.com.
