(CNN) -- Liza Long didn't think anyone would notice her blog outside of a small circle of friends. But she was wrong, way wrong. Millions of people were keenly interested in the Idaho mother's struggles with the 13-year-old son she loves and fears. A 40-year-old mother of four, Long teaches English at a small college in Boise. On Friday she posted a brutally honest essay on her blog, The Anarchist Soccer Mom. It struck a nerve in the wake of the mass shooting in which 20 children died at Sandy Hook Elementary School in Newtown, Connecticut. Over the weekend, it seemed, everybody was sharing the post and talking about The Anarchist Soccer Mom. Then came the backlash, as others criticized her for committing her son and writing about it publicly.
