I'll shoot the grammar nazi because that's not an acronym. That's an initialization. An acronym is an initialization meant to spell out something phonetically - such as D. A. R. E. or S. N. A. F. U. or F. U. B. A. R.
All acronyms are initializations while only some initializations are acronyms.
Grammar is the study of how words and their component parts combine to form sentences. Pronunciation is the supposedly correct manner of pronouncing sounds in a given language. Half his corrections are over pronunciation, not grammar. Plus I think the correct pronunciation should be "h-atch".
The only way I think that he might be suggesting that it's a tautology is that he spells it "whiskey," as opposed to the Scotch "whisky," but even that's not a tautology since the "e" spelling's used for American whiskeys as well.
So yeah. What the hell are you talking bout, Goethe?
