activist

n. supporter of activism, one who advocates active involvement as a means to achieve political or other goals

Activism, in a general sense, can be described as intentional action to bring about social or political change. This action is in support of, or opposition to, one side of an often controversial argument.The well known terms activism and activist used in a political manner first appeared in the Belgian press in 1916 in connection with the Flamingant movement. The word "activism" is often used synonymously with protest or dissent, but activism can stem from any number of political orientations and take a wide range of forms, from writing letters to newspapers or politicians, political campaigning, economic activism (such as boycotts or preferentially patronizing preferred businesses), rallies and street marches, strikes, or even guerrilla tactics. In the more confrontational cases, an activist may be called a freedom fighter by some, and a terrorist by others, depending on whether the commentator supports the activist's ends.
