On ongoing Twitter conversation is designed to draw attention to harassment, discrimination and violence experienced by women. Categorized under the hashtag #YesAllWomen, hundreds of thousands of women have shared their stories of date rape, misogyny and other examples of what women fear at the hands of some men, even if not all men (see also: #NotAllMen) engage in those behaviors.

The hashtag was created after Friday’s shooting spree on Isla Vista near the University of Santa Barbara, in which 22-year-old Elliot Rodger killed 6 people and injured 13 others before killing himself. In the days and weeks leading up to the attacks, Rodger posted a series of YouTube videos declaring his hatred of all women in part because of the rejection he claimed he suffered at their hands. The #YesAllWomen tweets began as a response to his comments.

By Tuesday morning, #YesAllWomen had been tweeted more than 1 million times. Follow the conversation here.
