Conservatism in a Nutshell
A man is lost in the woods and it starts snowing, off in the distance he sees a cabin. Slowly he makes his way only to find a locked gate, he rings the bell and a voice asks what he wants. He tells the voice his plight and is told by the voice that there is a church down the road and that they will pray for him.
Libertarianism in a Nutshell
The snow continues and growing more tired and cold, the man sees another cabin, struggling he barely makes it and knocks and finally opens the door to warm himself. There is a full kettle of hot soup, he helps himself. Soon out of a back room comes a man, he scolds the man and tells him to leave as this is private property. The man stumbles out the door.
Liberalism in a Nutshell
Nearly exhausted the man sees a third cabin. Slowly he makes his way, opens the door and warms himself. There is soup in a kettle and he helps himself. From a back room a woman enters, she sits down next to him and they talk. He sleeps the night on the floor and the next morning goes on his way.
