In early March, I met up with Jeffrey Goldberg, the editor in chief of the Atlantic, at an event sponsored by the magazine at the South by Southwest conference in Austin. He had just hired me away from National Review, the venerable conservative magazine where I’d been a writer and editor for 10 years.

“You know, the campaign to have me fired will begin 11 seconds after you announce that you’ve hired me,” I told him. He scoffed. “It won’t be that bad,” he said. “The Atlantic isn’t the New York Times. It isn’t high church for liberals.”

My first piece appeared in the Atlantic on April 2. I was fired on April 5.

The purported reason for our “parting ways,” as Mr. Goldberg put it in his announcement, had nothing to do with what I’d written in my inaugural piece. The problem was a six-word, four-year-old tweet on abortion and capital punishment and a discussion of that tweet in a subsequent podcast. I had responded to a familiar pro-abortion argument: that pro-lifers should not be taken seriously in our claim that abortion is the willful taking of an innocent human life unless we are ready to punish women who get abortions with long prison sentences. It’s a silly argument, so I responded with these words: “I have hanging more in mind.”
