Most of the uproar stemmed from the first tweet, which simply said "BREAKING: Witnesses reporting screams and gunfire heard inside Capitol building." Some people, including Chris Hayes, thought The Onion had been hacked; others apparently thought it was real. Michelle Malkin didn't think it was funny because it made light of a serious issue ("Maybe if some of these humorists had relatives who worked in the Capitol they would have thought twice"), while one of the people in the comments said it was "equivalent to yelling 'fire' in a crowded theater." Xeni Jardin of Boing Boing called the tweet "troublesome" because it didn't contain any "subtle indicators" of jokes like hashtags or links to longer comedy pieces, and insisted the joke had backfired (if her criteria for a backfired joke is "people fell for it," then every Onion article has "backfired"). Apparently people are calling it a #TWITTERFAIL (I involuntarily shuddered as I typed that) for The Onion.
Here's the thing, though. Yes, on its own, that tweet is not funny. But that's because it's not a joke. It's the SETUP to a joke. Imagine if these people read someone tweeting "Man walks into a bar..." They'd go "Whoa whoa whoa. They didn't make it clear this was a joke. There's no indication this was a joke aside from the fact it came from @funnyjokesontwitter.com. Where is the funny? There's nothing funny about a man walking into a bar. How can they joke about this when alcoholism is rampant? #notfunny #twitterfail #jokebackfire"
It reminds me of the insane overreaction to that great New Yorker cover satirizing Barack Obama conspiracy theories. I barely remember what the reasoning behind the overreaction was, something about how it wasn't clear it was a joke (obviously people should start putting JOKE ALERTS on jokes). In any case, pundits should stop playing Comedy Cops unless they have a degree from an accredited clown college.
