Some people are Freethinkers from sheer stupidity. My Uncle Sosthenes was one of these.
Some people are often religious for the same reason.
The very sight of a priest threw my uncle into a violent rage. He would shake his fist and make grimaces at him, and would then touch a piece of iron when the priest's back was turned, forgetting that the latter action showed a belief after all, the belief in the evil eye. Now, when beliefs are unreasonable, one should have all or none at all. My uncle was a Freemason, and I used to declare that they are stupider than old women devotees.
