Last Thursday, I received the news that the HuffPost Opinion section—where I’d been opining on a weekly basis for a few months—had been axed in its entirety. The same opinion column had had a home at The Village Voice for some 21 weeks before that entire publication shuttered as well. “This business sucks,” I tweeted, chagrined at the simple fact that I kept losing my column because of the cruel, ongoing shrinkage of independent journalism in the United States. Dozens of jobs were slashed at HuffPost that day, following a round of layoffs at Gannett Media; further jobs were about to be disappeared at BuzzFeed. It was a grim day for the media, and I just wanted to channel my tiny part of the prevailing gloom.

Then the responses started rolling in—some sympathy from fellow journalists and readers, then an irritating gush of near-identical responses: “Learn to code.” “Maybe learn to code?” “BETTER LEARN TO CODE THEN.” “Learn to code you useless bitch.” Alongside these tweets were others: “Stop writing fake news and crap.” “MAGA.” “Your opinions suck and no one wants to read them.” “Lmao journalists are evil wicked cretins. I wish you were all jail [sic] and afraid.”

I looked at the mentions of my editors, who had been laid off after years at HuffPost, and of other journalists who had lost their jobs. There they were, the swarm of commentators, with their same little carbuncular message: “Learn to code.”

On its own, telling a laid-off journalist to “learn to code” is a profoundly annoying bit of “advice,” a nugget of condescension and antipathy. It’s also a line many of us may have already heard from relatives who pretend to be well-meaning, and who question an idealistic, unstable, and impecunious career choice. But it was clear from the outset that this “advice” was larded through with real hostility—and the timing and ubiquity of the same phrase made me immediately suspect a brigade attack. My suspicions were confirmed when conservative figures like Tucker Carlson and Donald Trump Jr. joined the pile-on, revealing the ways in which right-wing hordes have harnessed social media to discredit and harass their opponents.

What’s a brigade attack, you may ask? It’s a rather dramatic name for coordinated harassment, usually migrating from one social media site to another. Often hatched in the internet’s right-wing cesspools, these campaigns unleash a mass of harassment on unsuspecting targets. 4chan’s /pol/ board—a gathering-place for people who want to say the n-word freely, vilify feminists, and opine on nefarious Jewish influence—has an oversize role in organizing brigade attacks, in part due to the fact that all its users are anonymous.
