LOL, the racism and sexism of the publishing industry? Some people have room to complain about that. But not Jessica Valenti.
Look, I can't tell you how I know this, but Jessica Valenti was given her first book deal and advance by a publisher in a way almost NO ONE gets a book deal. The editor contacted her, without her needing to get an agent or anything else, and held her hand through the writing of a book proposal (often the tough stage where writers get knocked back because of inexperience). All the stuff that's usually incredibly difficult -- writing and editing the proposal, shopping it, understanding competitive books and pitching the proposal at a publisher's meeting -- she was shepherded through it all by her editor, who gave a series of similar book deals to other feminists with prominent blogs.
It's hard to overestimate the value of this kind of jump start to a writing career for any fledgling blogger. Now, Valenti and several other women who got those book deals are considered big-name feminists who can command significant fees just for appearing on college campuses and such.
Way back when she was first getting book deals of this sort, a black feminist blogger noticed that the publisher and editors weren't publishing books by black authors. The response of both the white feminist bloggers like Valenti and the editor who'd been greasing their way was "well, black authors just don't submit book proposals." They wanted to completely obscure the fact that Valenti & co. hadn't just gotten in on their merits, by submitting a proposal like anyone else, but instead had significant help of a sort that not one writer in a hundred gets in their career. To this day, they won't admit that they got help in ways that those black feminist authors were never offered. Very "intersectional."
