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.
About a century ago, blackface was a form of comedy where white people would make their faces black and put on comedic shows. They would take some elements of black culture, like mimicking accents or saying they love fried chicken and watermelon, and make fun of black people for being idiots.
Giving out fried chicken to an event like this feels like you don’t really care about the event. Instead, it is a token gesture at best where the decision makers thought “well, black people like fried chicken, so give them that.”
Watermelon and other red food is served on Juneteenth. But, if watermelon is the only red food there, they likely didn’t pick it because of cultural sensitivity to the holiday.
IDK, the National Museum of African American History serves fried chicken every day, so they don’t think there’s anything wrong with it.
Interestingly, if you look at the menu for Juneteenth, it doesn’t include fried chicken. The only chicken is a dry rub chicken that wouldn’t be fried. So your evidence confirms they believe fried chicken is in fact not appropriate for Junteenth. That’s a good reference point if we all accept that the national museum of African American history is an authority on such matters.
