Really interesting question. As some others have pointed out, if we're materialists, as a lot of people are here, our instinct is to look first to the material conditions that produced GamerGate. But stopping there elides some interesting questions. If we accept that some sort of far right resurgence was inevitable, did it have to take the form of GamerGate? If so, what about this particular moment in history made it inevitable? If not, why then did it take the form of GamerGate and not something else? What other possibilities were there?
