"Anarchists reject centralization of authority and the concept of a . All groups are free associations formed out of committees not revolutionaries disciplined by fear of authority. When the size of the work-groups (which could be fanned around Labor, fundraising, anti-racism, women’s rights, food and housing, etc.) becomes cumbersome, the organizations can be decentralized into two or several more autonomous organizations, still united in one large federation. This enables the group to expand limitlessly while maintaining its anarchic form of decentralized self-management. It is sort of like the scientific theory of a biological cell, dividing and redividing, but in a political sense. However, Anarchist groups aren’t even necessarily organized loosely; Anarchism is flexible and structure can be practically nonexistent or very tight, depending upon the type of organization demanded by the social conditions being faced. For instance, organization would tighten during military operations or heightened political repression."
