Fish has been involved with numerous political causes, most notably anti-war activism during the Vietnam War, and is a longtime member of the Industrial Workers of the World, a fact referred to in several of her songs (e.g., "Wobblies From Space", "Leslie's Filks"). She is also well known as a gun-rights activist, and has asserted that private gun ownership is the only true protection of individual freedom (a topic touched on in several of her songs). Because of her distrust of the stability of modern society, she has in the past worked to organize groups for carrying on civilization after what she (at one time at least) considered the imminent collapse of the current society. Her album "Firestorm" was in large part meant as a set of instructions for surviving a nuclear war, on the reasoning that it would be easier to recall them if they were in lyric form.
