A number of months ago, I listened to a podcast that has haunted me since — because it captures something essential about our culture warrior moment. It was from NPR’s always excellent “Invisibilia” series and it was about a woman named Emily.

Emily was a member of the hard-core punk music scene in Richmond, Va. One day, when she was nearly 30, she was in a van with her best friend, who was part of a prominent band. They were heading to a gig in Florida when the venue called to cancel their appearance. A woman had accused Emily’s best friend of sending her an unwelcome sexually explicit photograph.

His bandmates immediately dismissed her allegations. But inwardly Emily seethed. Upon returning to Richmond, she wrote a Facebook post denouncing her best friend as an abuser. “I disown everything he has done. I do not think it’s O.K. … I believe women.”

The post worked. He ended up leaving the band and disappeared from the punk scene. Emily heard rumors that he’d been fired from his job, kicked out of his apartment, had moved to a new city and was not doing well. Emily never spoke with him again.
