Apparently, SXSW has canceled a pair of panels—one about the evils of online harassment, one that seemed supportive of GamerGate—due to threats of violence. Here's Kotaku:
Word began to circulate on Twitter this afternoon that South By Southwest had cancelled two gaming panels, one "regarding the current social/political landscape in the gaming community," the other on "online harassment in gaming and geek culture." Though it didn’t respond to Kotaku’s requests for comment, SXSW interactive director Hugh Forrest published a statement.
In it, Forrest said that SXSW hoped "hosting these two discussions in March 2016 in Austin would lead to a valuable exchange of ideas on this very important topic," but the alleged threats prompted them to reconsider.
Look, this isn't rocket science: if you cancel events because people threaten violence it only emboldens people to threaten violence in the future when they hear of events they don't like. If you're legitimately worried about violence, hire some security (given that SXSW doesn't pay most of their acts or, IIRC, their presenters/panelists, I imagine they can afford it). That being said, you don't need to be worried about violence. These men are cowards, Donnie. And if you start standing up to them, they will, like all cowards, go away.
But the worst thing you can do—the absolute worst thing you can possibly do—is to cancel a panel about online harassment after a few idiots hop online and start harassing people. You are literally letting terrorists win. Knock it off, dumb dumbs.
