These people, for the most part, do not respond or even seem to comprehend correction. They seem to be the same people that refuse to understand what is going on when they dial a wrong number: "Hey Stan! What's goi-" "I am not Stan. You have the wrong number." "No, this is Stan's number." "....click"

If you can't apply the term "idiots" to these people then the word is useless and can never be used.
