"Moral indignation is jealousy with a halo." -- H.G. Wells
I've often been mystified at the intense emotions of those usually religious people who become outraged when other people don't live according to their rules. Perhaps Mr. Wells is onto something. The idea that the strongest homophobes are repressed homosexuals is a cliche, but maybe a similar mechanism is at work for all of the loudest proponents of "morality." Maybe they want to have sex how they want and eat what they want and watch what movies they want. Maybe they want to look at all forms of art and listen to all kinds of music. Maybe they just want to read secular philosophy. Maybe deep down they're afraid that they're passing on these parts of life for no reason and so they must shout out the doubts in their own minds.
