When you witness a woman being catcalled or groped in public, is the first impulse to intervene? Or do you fear for your own safety as well? Holly Kearl, the author of Stop Street Harassment! Making Public Spaces Safe and Welcoming for Women and founder of the blog of the same name, says that gender-based harassment in public space continues to be acceptable largely because bystanders and victims are taught to ignore it. “Harassers and abusers continue to harass and abuse when they know they can get away with it, and bystanders can do a lot to stop them from getting away with it,” Kearl explains.
