In the video above, Sargon takes a few minutes to make fun of a social justice warrior's stated desire that teachers countenance language anarchy in their classrooms for the sake of "marginalized populations" who may not feel "comfortable" using received American English. He's right on point when he argues that this proposal is racist; African-Americans are not uniquely incapable of learning the dominant - or correct - grammar and don't need to be molly-coddled by their instructors just because they use AAVE at home. To assert that black students should be granted special dispensation is basically enhancing any stigma that may be attached to AAVE by implicitly suggesting that its users are too stupid to learn something else.
But I'd like to add another point: This "researcher" - and interviewing a few people on your campus is not actually research, cupcake - has no clue what it's like to be white. Like every other social justice cultist, she presumes that white people never have to "code switch" and never deal with any stigmas attached to their manner of speaking. This is just not true. As anyone from the Southern U.S. or the Appalachian region will tell you, there is plenty of negative baggage attached to white dialects that don't fit the broadcast norm. Southerners and mountain folk are assumed to be idiots as a matter of course -- not to mention racist, sexist, homophobic bigots whose laughable idea of high art is a NASCAR race. If you're southern, you could be Doc freakin' Taylor - a bona fide rocket scientist - and yet still have to present your CV to elitist northerners before they'll accept you know what you're talking about. But nobody is talking about giving "hillbillies" and "rednecks" a pass on the whole standard grammar thing. My friends and acquaintances down here just accept "code switching" as a fact of life -- like, for example, my AP US History teacher twenty years ago, who admitted freely in class one day that when he goes back home to West Virginia, his style of speech completely changes on a dime. "I'm not Mike anymore. I'm Maaaaaaaaaike."
TL;DR: Academia is once again rewarding ignorance. White people do "code switch" and do deal with stigma. People suggesting otherwise can kindly sit on a certain finger and rotate.
