Fraternity Closed over Rape Survey

This AP/Columbus Dispatch article entitled "Fraternity Closed Over Rape Survey" reports that a fraternity in Vermont had distributed among its members a survey asking who they would like to rap. On the heels of a recent national survey that found 1 in 5 women have been sexually assaulted ("Nearly 1 in 5 Women in the U.S. Survey Say They Have Been Sexually Assaulted"), how do you think this issue should have been handled? Why is sexual assault a continued issue, especially on college campuses?
