Crandall's asininity is a medical condition verified by a doctor. It is called pinecone-upper-anum.
However, to understand Rajani, we have to consult a standard IQ chart where 100 is considered average. Let's not give him too much credit, so we'll start at the bottom and work our way up...
An idiot has an IQ of 0-25.
An imbecile, an IQ of 26-50.
A moron has an IQ of 51-70.
A nutjob has an IQ of 71-80.
A prichk has an IQ of 81-90.
A dichk has an IQ of 91-99.
A jackass is a nutjob with a prichk of a dichk so small it's immeasurable.
By my calculations, Rajani is a bit of a jackass.
Good news is, only idiots are considered by law to be too incapacitated to commit a crime. Therefore, Rajani can be charged for his intransigence of ignorance.
It's true — there's a difference. The three terms didn't start out as social insults either, in fact. In the early 1900s, psychologists used the terms to describe various levels of retardation. Those with an IQ of 0 to 25 (an IQ of 100 is average) were called idiots, 26 to 50 were called imbeciles and 51 to 70 were called morons. Morons could communicate and learn common tasks; imbeciles stalled mentally at about six years old; and idiots couldn't respond to stimulus or communicate with any level of competency.
Regarding the entire leadership of the SLN, the mother of a mental giant by the name of Forest Gump said it all...
"Stupid is as stupid does."
