As national editor of Politico Magazine — an opinion outlet — Michael Hirsh used social media to tee up some spicy commentary. Examples:

Then he went too far. He posted this note to Twitter on Monday:

Scary as that post is, Hirsh escalated things on social media Tuesday (his Twitter and Facebook accounts appeared to have been linked, but the links have been deleted). Perhaps figuring that his previous missive was too vague, he decided to put addresses in the mix: “Stop whining about Richard B. Spencer, Nazi, and exercise your rights as decent Americans. Here are his two addresses,” wrote Hirsh. When a do-gooder questioned on Facebook why people needed his address — “Send a letter? Confront him in person?” — Hirsh replied, “I wasn’t thinking of a f—ing letter. … He lives [gives approximate location]. … Our grandfathers brought baseball bats to Bund meetings. Want to join me?”

Herewith a pretty easy call for Politico editor Carrie Budoff Brown and editor in chief and publisher John Harris, who issued this statement: “These posts were clearly outside the bounds of acceptable discourse, and POLITICO editors regard them as a serious lapse of newsroom standards. They crossed a line in ways that the publication will not defend, and editors are taking steps to ensure that such a lapse does not occur again.”

Hirsh has resigned, as reported by the Daily Caller. He landed at Politico from National Journal in 2014.

As for the “steps” that Politico editors are taking to prevent a recurrence of this kind of episode: That’s an admirable response, though it should go without saying that news professionals shouldn’t post the addresses of newsmakers in threatening contexts.

Corrected to note that Hirsh was national editor of Politico Magazine, not regular old Politico
