  • "And whatever its shortcomings as a means to social change, protest movements keep reinventing carnival. ... The media often deride the carnival spirit of such protests, as if it were a self-indulgent distraction from the serious political point. But seasoned organizers know that gratification cannot be deferred until after 'the revolution.' ... People must find, in their movement, the immediate joy of solidarity, if only because, in the face of overwhelming state and corporate power, solidarity is their sole source of strength."
