A more thorough explanation:

An anarchist is someone who believes that organized government should be overthrown by force or that a society without government is the best political system. This belief is called anarchism.

• Emma Goldman was a famous anarchist who believed in the abolition of government and capitalism.
• The Black Bloc is a group of anarchists who use violent tactics to protest against government and corporate power.

These examples illustrate the definition of an anarchist because they both involve individuals or groups who reject the idea of organized government and advocate for its overthrow. Emma Goldman believed that government was oppressive and that individuals should be free to govern themselves. The Black Bloc uses violence to disrupt the power structures they see as oppressive and to create chaos in the hopes of sparking a revolution.
