"completely incorrect" is useless prescriptivism. They can call it incorrect all they like, it won't stop anyone.

[D_Alex]

It may be ineffective prescriptivism. The usefulness is in the fact that we should have a word that unambiguously means "in a strict sense, without exaggeration".

What is kind of useless is a word that can mean some thing or its opposite, and there is no way to tell from the context, eg:

"When the tiger went "Rawr! Rawrrr!", I literally fouled my breeches!"

>the fact that we should

Can't have a factual should. Shoulds are normative.

>What is kind of useless is a word that can mean some thing or its opposite

Is the word really useless or indeed useful if no one can provide a 'real' example of actual ambiguity between the two meanings? Furthermore, it's not as if ambiguity between one meaning and an opposite meaning is the greatest ambiguity there is-- if anything, it makes it particularly obvious which meaning the speaker intends.

[Chris2048]

Surely you can if a source of reference is used? i.e "fact we should" = "fact that most of society believes we should"?

But more, it misunderstands a dictionary's purpose, which is to dispassionately list how people choose to use words.

[D_Alex]

Not according to dictionary.com - that says that the purpose of the dictionary is to provide information on meaning and correct usage of the word.

Also, Wikipedia refers to two types of dictionary: prescriptive and descriptive. But even the descriptive type should provide information on how the word is used, eg: "sometimes incorrectly used to mean 'figuratively'".

Wait, think a minute. That description exactly corresponds with what I said. The "correct" usage of a word is precisely, exactly what the speaker thinks it means, at that moment in time.

If a dictionary listed a definition that was not in use by anyone, that would be different -- that would be incorrect.

Yes, and there are no prescriptive dictionaries, at least not in English. The French have one, created by the Académie française:

Apart from the French example, it seems telling people how to use words has fallen out of fashion, giving way to another example of evolution by natural selection.
