That being said, I can see how it would be bothersome especially if a source of the confusion was due to something I'm sensitive about. I imagine (from your post) it'd be like if somebody mixed you up with "that other guy who isn't good enough to be a front end engineer". Even if both of you were plenty qualified to be front end engineers, due to your sensitivity it might be a little bit more raw. Thankfully most of us don't have to walk around with evidence of our sensitive issues all over our bodies.
I would imagine, without going too far down the research rabbit hole (because this is a close topic to me being both black and a lover of food history in general) that the whole "fried chicken and watermelon" thing are likely poorly understood branches coming from that evolutionary tract.
Take Huey P. Newton for example, I've had plenty of frank, honest and open discussions with individuals who want to tell me everything they know about Huey P. Newton and his "radical-ness" and his "anger" and his "passion" as a Black Panther because of whatever oral tradition they've had passed down to them informing their viewpoint of the man-but it never goes very far beyond surface-level descriptions, and rarer still his philosophies or doctoral essays. Substitute Newton with James Baldwin, Clarence Thomas, MLK, heck even Dr. Cornel West.
I think the same unfortunate blurring of the culinary traditions of Black Americana has happened re: Fried Chicken and Watermelon-thin, surface-level oral traditions passed down time and time again until we got where we are now "Fried chicken, watermelon and purple koolaid" are for good or ill tied into every conversation of "black foods".
And not to derail the conversation, but as a fellow Boulderite who desperately misses having a a Popeyes within 20 minutes, have you found any good fried chicken places? I have yet to find anything besides Yellowbelly and the exceptionally terrible KFC on Arapahoe.
But my God are are you brave for using that handle on HN, sir.
