Antifa
A loose association of anti-racist groups who engage in popular resistance to fascism. Antifa members recognize the state's refusal to take action against fascist violence and are thus forced to take matters into their own hands to protect their communities.

Antifa members are historically literate and have studied how European fascists used free speech and free assembly as weapons to seize control of their governments and ultimately do away with such liberties. They understand that Nazism and fascism are fundamentally violent, dictatorial ideologies that must be squashed and will exhaust all nonviolent means before resorting to defensive violence.

The establishment vilifies Antifa groups as "terrorists" precisely because they challenge the white supremacist social order and frustrate the ability of white supremacists to use racial minorities as punching bags.
Cornell West: "If it hadn’t been for antifa protecting us (black Charlottesville clergymembers) from the fascists, we would've been crushed like cockroaches."
