Disclaimer: I am not trolling, I am an autistic person who doesn’t understand so many social nuances. Also I am from New Hampshire (97% white), so I just don’t have any close African-American friends that I am willing to risk asking such a loaded question.
The history of forcing slaves into limited food choices, and then caricaturing an entire race based on people adapting to those arbitrary forced limits…there are alot of layers of historical racism in play that could make doing this in a way that highlights those foods would probably play into that racism. Chicken and watermelon aren’t “black” foods, they were common staples of Southern slaves that had limited choices.
That said, those stereotypes are stupid, those foods are delicious to people of all races, so if those foods are served as a broader celebration or feast and its just part of the day without any emphasis or indicators of meeting (i.e., chicken and fruit are common foods for celebration so why not have them), I don’t think anyone would care.
