So, what is SlutWalk? From Wikipedia:
SlutWalk is a transnational movement of protest marches which began on April 3, 2011, in Toronto, Ontario, with subsequent rallies occurring globally. Participants protest against explaining or excusing rape by referring to any aspect of a woman's appearance, and call for an end to rape culture. The rallies began after a Toronto Police officer suggested that "women should avoid dressing like sluts" as a precaution against sexual assault.
The protest takes the form of a march, mainly by young women, where some dress as "sluts" in revealing, sexy attire such as short skirts, stockings and scanty tops. In the various Slutwalks around the world, there are usually speaker meetings and workshops, live music, sign-making sessions, leafleting, open microphones, chanting, dances, martial arts, and receptions or after-parties with refreshments. In many of the rallies and online, women speak publicly for the first time about their identity as rape survivors. The movement's ideology has been questioned and its methodology criticized.[12
