Activism takes many forms. It can be as complicated as a class-action lawsuit or as simple as wearing a T-shirt.
Certain kinds of activism are unquestioned as part of social citizenship, such as voting, being informed, and going to school. People engage in other forms of activism, such as petitioning and protest, when rights are denied.
"The notion that any one person is the single cause of any significant social change—that Abraham Lincoln alone freed the slaves—is a devastating stereotype which robs individuals of responsibility and credit, and actually inhibits social change.... You can be a revolution of one. In your living room, in your family, in your community." —Justin Dart, 1998
