"In medicine and psychology, an idiot is a person with a very severe mental retardation or a very low IQ level. Idiots were defined as people whose IQ were below 20 (with a standard deviation of 16). In the current classification, these people are now said to have profound mental retardation. The word is no longer used as a scientific term.
The word is derived from the Greek word ιδιωτης, iditês, "a private citizen, individual", from ιδιος, idios, "private". In ancient Athens, an idiot was a person who declined to take part in public life, such as democratic city government. Since such activities were honorable and could directly affect all citizens, idiot was a term of derision."
So, maybe instead calling people "idiots" Murtaza should be saying that they suffer for profound mental retardation?
Or maybe Murtaza was angry that you didnt take part in last elections? So therefore you are an idiot - in meaning of this word which was used in ancient Athens?
