To follow up you might want to catch the six minute Morning Joe interview here. In the interview Jessica talks about the "but" aspect of this subject. She speaks about how people often speak of a rape victim saying how awful that was and sometimes add a "but" as in "I wish that she did not dress that way" or "she was asking for it by dressing like that". She also points out that the victims of rape are, generally speaking, not those who dress slutty.
The protests began after a police officer told students at Toronto’s York University in January that if women want to avoid rape, they shouldn’t dress like “sluts.” (If you thought the days of “she was asking for it” were long gone, guess again.)
Heather Jarvis, a student in Toronto and a co-founder of SlutWalk, explained that the officer’s comments struck her and her co-organizers as so preposterous and damaging that they demanded action. “We were fed up and pissed off, and we wanted to do something other than just be angry,” she said. Bucking the oft-repeated notion that young women are apathetic to feminism, they organized. What Jarvis hoped would be a march of at least 100 turned out to be a rally of more than 3,000 — some marchers with “slut” scrawled across their bodies, others with signs reading “My dress is not a yes” or “Slut pride.”
I applaud the organizers of these walks and appreciate the attention that they bring to this important issue of sexual violence. In response to my post some may want to bring up the issue of women's clothing. If you do then I think that you have missed the point entirely.
