Issues that fourth-wave feminists focus on include street and workplace harassment, campus sexual assault and rape culture. Scandals involving the harassment, abuse, and murder of women and girls have galvanized the movement. These have included the 2012 Delhi gang rape, 2012 Jimmy Savile allegations, the Bill Cosby allegations, 2014 Isla Vista killings, 2016 trial of Jian Ghomeshi, 2017 Harvey Weinstein allegations and subsequent Weinstein effect, and the 2017 Westminster sexual scandals.
