What is taking place here is a kind of silencing. Defining people as "violent" is fundamentally a way to delegitimize them; Solnit and Hedges feel entitled to spread falsehoods about their political adversaries because their goal is to shut them out of the discussion entirely. That's why Hedges acknowledges he never spoke to anyone involved in a black bloc in the course of composing his diatribe. Perhaps we shouldn't expect better from journalists with their own wikipedia pages and glamor shots, who have much to lose should popular movements cease to be managed from the top down.
To counteract this silencing, we sought out our comrades from the heart of the black bloc and asked them to tell their side of the story: where they come from, why they participate, how they see the world. We do not accept the terms set by the mudslingers: our intent is not to compete for ideological legitimacy on a battlefield of abstractions, but to foster mutual understanding grounded in personal experience. As the expression goes, God only knows what devils we are: He can't know anything else.
