In addition, there are the continuing problems of dismal representation of women in Parliament (where men outnumber women four to one), the enduring gender pay gap (where women working full time earn 16 percent less than men) and the continued scarcity of women in the most senior positions in business and politics. Ms. Banyard is particularly concerned by the “relentless objectification of women which is the cultural backdrop in the U.K. — the pornified norm, on mainstream television.”

“Because of the ease with which people can share pornography on their mobile phones, it has never been easier to access really violent or degrading images of women,” she says. “We are being confronted with it more and more — things like upskirting on mobile phones.

“This all adds up to an urgency. It should be a political priority, but these issues are sidelined and not seen as the disaster that they are. Most people believe in the idea of equality between the sexes; notionally, people support it, but we are a long way from realizing that aspiration.”

The growing interest in a new wave of feminism in Britain is echoed in a recent spate of feminist publications, with books like “Reclaiming the F Word,” on contemporary feminism; Caitlin Moran’s “How to be a Woman”; Cordelia Fine’s “Delusions of Gender”; and Natasha Walter’s “Living Dolls: The Return of Sexism” all doing well.

“From my perspective, the debate has shifted from the perennial ‘Where is feminism?’ debate to ‘What can this resurgent feminism achieve?”’ Ms. Banyard says.

The summer camp will help women — and men — channel their impatience at the slow pace of change into noisy protest. Campaigners are already planning when to put their new skills into action. Politicians should expect some form of yet-to-be-revealed mass feminist action outside the House of Commons in late October. More imminently, Ms. Banyard says, delegates at a European trade gathering for the pornography industry, due to meet for an annual conference at a London hotel, should also be bracing themselves for protest.

As well as providing lessons on how to occupy a public space during a protest, the summer camp aims to be an upbeat meeting place for a group of campaigners who still feel resented.
