Activism is the practice of vigorous, intentional action to bring about social, political, economic, judicial, and/or environmental change. This action is in support of, or in opposition to, one side of a controversial argument.
Activism is often used synonymously with free speech, demonstration, protest or dissent. Activism can stem from any number of political or social orientations and take many forms, from letter writing and video taping to political campaigns, boycotts, rallies, street marches, work stoppages and hunger strikes, or even guerrilla tactics.
In some cases, activism has nothing to do with protest or confrontation. Some religious, feminist vegetarian/vegan or political activists seek to persuade people to change their behavior directly, rather than to persuade governments to change laws. Cooperative movements such as www.titania.org and www.AOCS.com seek to build new private institutions, which conform to cooperative principles without the use of government.
