In an online world increasingly filled with harassment and trolling, women bear the brunt of hostile sexual messages. Over half of young women say they've been sent explicit images that they didn’t ask for, according to Pew. After one too many of these hostile encounters, Alexandra Tweten created the viral Instagram account @ByeFelipe, which calls out men who turn hostile when rejected or ignored. Her new book, Bye Felipe: Disses, Dick Pics, and Other Delights of Modern Dating blends humor and feminist theory to showcase the worst examples of online sexist behavior, explore why men harass women in this way, teach women tactics they can employ to fight back, and solutions for what we can do about the trolls.
