Bookworms Battle Trolls

On Monday night, while feeding his 1-year-old son, Chris Currie encountered what many women and few men have to confront: vicious online attacks from anti-feminist trolls.

“It was a bit of a shock,” he told us on Wednesday.

All he’d done was publish a short post that morning on the Facebook page of Avid Reader, a Brisbane independent bookshop where he’s the social media manager. It simply celebrated the news that Clementine Ford, the Australian feminist author and commentator, had secured a publishing deal for her second book.

But that was enough.

Bad reviews on Avid Reader’s Facebook page flooded in. Mr. Currie’s phone was inundated with abusive messages. The notifications were wild, violent, persistent — and all from men.
