Camp taste is, above all, a mode of enjoyment, of appreciation - not judgement. Camp i s generous. It wants to enjoy. It only seems like malice, cynicism.
Camp is the consistently aesthetic experience of the world. It incarnates a victory of "style" over "content", "aesthetics" over "morality", of irony over tragedy.
Things are camp, not when they become old - but when we become less involved in them, and enjoy, instead of be frustrated by, the failure of the attempt.
