The slutwalk phenomenon does more harm to women than good, warns international anti-porn campaigner Gail Dines.

Professor Dines, a fierce critic of raunch culture who is touring Australia this month to promote her book Pornland, said that protest marches that aim to reclaim the word "slut" would only reinforce stereotypes.

"By having a slutwalk, you have turned the focus onto what women are wearing," Professor Dines told The Age. "The men who are responding to this message are not getting the irony at all." By dressing in fishnets and push-up bras and brandishing 'slut" signs, she said, the organisers are playing into the hands of raunch culture. "Men want women to be sluts and now they're buying in."

The day before before Australia's first slutwalk sets off from the front steps of Melbourne's State Library on Saturday May 28, the professor will be speaking at the library's Wheeler Centre on the pressure young women feel to live up to the images available on internet porn.

"Young women today have two choices," she said, "to be f***able or invisible. If the only choice is to be hypersexual, you cannot call it a meaningful choice. In the US, even women who read the news, even politicians have to be [sexy]".
