The Hedonist International is a very liberal yet very social idea and community of people who have some very unconcrete ideas about politics but very concrete and unusual methods of actions, e.g. entering the tv tower of Berlin and turning the slow moving tourist viewing platform (and old-fashioned restaurant) into a gigantic party space or pro-war demonstrations.
“The Hedonist International wants joyful togetherness, anarchy, epicurean ideas, multifaceted joy, sensuality, diversion, friendship, justice, tolerance, freedom, sexual freedom, sustainability, peace, free access to information, the arts, a cosmopolitan existence, and a world without borders or discrimination, and everything else that is wonderful but not a reality today.”
