@JTT,
I have offered plenty...but you are simply arbitrarily deciding what I offer does not count.
You claim that “There are no language scholars at all who subscribe to that errant, outdated notion, Frank. Why? Because it is simply unsupportable.”
The “errant, outdated notion” in your comment refers to the concept of "good English grammar" and "poor”…as amended several times to “acceptable English grammar” or “standard English grammar.”
So you are saying there are no language scholars AT ALL who subscribe of the concept of “good, acceptable, or standard English grammar” and “poor, unacceptable, or non-standard English grammar.”
I think you are completely, utterly full of **** on this.
I have produced several books written by language scholars that even have in their title “good English grammar”…and all of which have the notion of “standard and non-standard” English grammar. Library shelves are filled with books on the subject; bookstores have stocks of books on the subjects.
All you have done is to classify any book that disagrees with this preposterous notion of yours…as non-language scholars…in order to make your stupidity stand.
Ain’t gonna happen, Asshole.
