"Unlike other streams of political thought, Anarchists do not elevate certain texts or individuals above others. There are different types of Anarchists with many points of disagreement. The primary areas of debate among Anarchists relate to what form of organization should be struggled for and what tactics we should use. For instance, some of their most significant differences concern the economic organization of future society. Some Anarchists reject money, and substitute a system of trade in which work is exchanged for goods and services. Others reject all forms of trade or barter or private ownership as Capitalism, and feel that all major property should be owned in common. There are Anarchists who believe in guerilla warfare, including assassination, bombings, bank expropriations, etc., as one means of revolutionary attacks on the State. But there also are Anarchists who believe almost exclusively in organizational, labor or community work. There is no single type, nor do they all agree on strategy and tactics. Some are opposed to violence; some accept it only in self-defense or during a revolutionary insurrection."
