I see dead people
There's this boy who could see dead people. He was haunted by them to such an extent that he could not make out the difference between the living and dead. He had been taught to fear the dead, so he did, except that he could not separate them from the living.
I see stupid people. They're all around. I don't know what their purpose in life is. Frankly, I don't think they even have a purpose. They breathe, because they'd die otherwise. They go to work, because they'd die otherwise. They marry, because the society wants them to. They breed, because the society would kill them otherwise. There's not one thing that they'd do if not by a force threatening of something more devastating. They're like a paper boat being carried along by the river's current. They don't have a will of their own. They're not alive.
The difference between dead people and stupid people however is that stupid people are easier to identify. Their actions follow no logic. You could identify them with just an imbalanced mathematical equation. It's so mundane that you could almost automate the process, the input being a stream of people and the output being a binary flag associated with each indicating whether or not he's stupid. It's a bit more complicated than that since the classification is not black or white, but a rounding off can be performed.
The problem after classification however is what to do with the stupid people. I would gladly leave them alone but they don't leave me alone. They make life difficult for me. They take my money in the name of law, they haunt me in the name of society and they try to stop me in the name of progress. They run the government, they make the rules, they pass judgments and then they decree punishment.
It's not like they'd understand logic. I don't want them to understand logic, as long as they leave me alone. Just leave me alone. I don't want you, I don't want to talk to you, I don't want to hear you. I don't want to see stupid people. I'd gladly see dead people instead.
