Other forms: anarchisms
If you're a proponent of anarchism, you believe in a political system that does away with all government.
Someone who favors anarchism can be described as an anarchist, a person who places the most political importance on individual freedom, especially from powerful governments. Anarchism is a political philosophy that opposes hierarchies — systems in which a more powerful person or group is in charge — and favors equality between all people. The Greek root word of anarchism is anarkhia, "lack of a leader," or "the state of no government."
