When the politicians talk about freedom, brotherhood or equality they are just trying to justify the prevailing inequality. The state is not an everlasting nor divine system. Its birth is closely related to the birth of capitalism. The state is anyhow seeing its own existence as a self-evident fact. That way it is trying to silence all the alternative ideas.
Anarchism means the demolition of the prevailing, state centric system.
The anarchist alternative means a humane and community centric way of life where the environment and people are what count - not only tools in the capitalist mass production and wage slavery system or a part of a humiliating machinery. We are trying to destroy the prevailing organisations, institutions and ways of thinking based on exploitation, oppression and subjection. These are sexism, racism and nationalism as well as wage labor and twisted parliamentarism as well as the education system and the church. The theory of anarchism is not able to say what the anarchist society in future will be like. Decisions made in advance tend to lead to a dead end where social openness and change are impossible.
