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.
Ignore what everyone on the internet says. They are wrong. Eat what you want. Just make sure everybody participating is comfortable. If you're not sure then ask them directly and listen to what they say.
The issue is that there is a cultural celebration involving food. Rather than try to serve food that fits within that cultural celebration, food was served based on a racial stereotype.
