If the definations are still quite applicable, what is the definition of person with an IQ between 0 and 25 if you can't use the term "idiot"?
That question is nonsensical.
Make up your mind. Do you want the definition or do you want the term. They are not the same. The definition of an "idiot" is "a person with an IQ between 0 and 25".
And, by the way, you can use the term idiot. It's just that some liberals have decided you shouldn't because that term is politically incorrect. It's similar to driving 60 in a 55 zone. Just because someone says you shouldn't drive over 55 doesn't mean you can't.
You really are dense (and tiresome, I might add).
