One of the better anarchist responses to Chris Hedges' 2012 infamously specious critique of the Black Bloc (in which he calls the Black Bloc a cancer).

What they find so disturbing about the black bloc--the contagion of an anonymous collective force--is precisely why and how it continues to outlive every social movement from which it emerges. These generations--we who fantasized about Columbine and now only know metal detectors at school; we who expected September 11 and now only the politics of terror; we who grew up as the world crumbled all around us and now only know the desert--we need to fight, and not just in the ways our rulers deem justified and legitimate.
