From Unofficial Handbook of the Virtue Universe
An activist is someone who takes action in support of or opposition to a cause. Activism can take a range of forms, from writing letters to government representatives to organizing boycotts. Some activists engage in radical or even illegal activity to further their ends, while others prefer to stay within the boundaries of the law to win more supporters to their causes. Activists can organize for a wide number of causes. Political parties, the environment, social justice, and moral issues are all common rallying points for activists. Some people participate in activism because they have personally experienced injustice or prejudice, while others simply believe in the cause they support or oppose, regardless of personal experience.
