Insurrectionary anarchism is a revolutionary theory and tendency within the anarchist movement that emphasizes insurrection as a revolutionary practice.[1][2] It is critical of formal organizations such as labor unions and federations that are based on a political programme and periodic congresses.[1] Instead, insurrectionary anarchists advocate informal organization and small affinity group based organization.[1][2] Insurrectionary anarchists put value in attack, permanent class conflict and a refusal to negotiate or compromise with class enemies. https://en.wikipedia.org/wiki/Insurrectionary_anarchism
