Jessica Valenti is one of the most successful and visible feminists of her generation. As a columnist for the Guardian, her face regularly appears on the site’s front page. She has written five books, one of which was adapted into a documentary, since founding the blog Feministing.com. She gives speeches all over the country. And she tells me that, because of the nonstop harassment that feminist writers face online, if she could start over, she might prefer to be completely anonymous. “I don’t know that I would do it under my real name,” she says she tells young women who are interested in writing about feminism. It’s “not just the physical safety concerns but the emotional ramifications” of constant, round-the-clock abuse.
