I think it's dangerous to put so much value on the absolving force of laughter. I believe that, in today's societies, laughter is "part of the game," so to speak. We believe we're achieving a cynical or ironic distance from the subject matter by laughing at it; that we're making for ourselves a kind of enlightened space from which we can objectively weigh others, while innocently poking fun at them and at ourselves. Personally, I don't believe there exists any kind of enlightened space, and I think that laughter allows us to delude ourselves into thinking there is.
