You, sir, are simply ignorant, but go sashaying about FR as a grammar Nazi, ‘correcting’ what you perceive to be a grammatical error. I simply pointed out to you that what had got your grammatical nose out of joint was not an error by the most relevant common standards.
In response, you have been insulting and you have only further demonstrated your limited understanding. The MLA published a separate document for writing in the academic world before the 1980s, when it first weighed in with a manual of style intended for the broader world.
I have a graduate writing degree and have worked professionally as a writer and editor for decades. I have tried to broaden your perspective by referring you to multiple appropriate and accepted authorities, and I am done with this conversation.
*My* dogs are all whos and whoms, “grammar rules” be damned.
