Subtle racism?

What is it with black people and McDonalds? Last night I saw a commercial for some "southern style" chicken sandwich that had two black women discussing the culinary arts, specifically putting chicken into a paper bag and shaking it. One woman said, "Remember when grandma taught us how to do this?" The other replied, "Yeah, and remember that time the bag broke open and flour went everywhere?" Then they both force a laugh, as if the scenario were extremely detailed and the viewer finds the situation hilarious themselves. Cut to a picture of the sandwich, with a voiceover of how excellent it is, with all those "southern flavors". What the fuck is a "southern flavor" anyway? It's supposed to be analogous to fried chicken, I'm assuming; why not just say that? Well, they have to appeal to the black people who just love fried chicken and whose grandmothers used a paper bag to make it. Apparently, "southern flavor" is code for black people food. After the picture of the sandwich, the commercial goes back to the women, who are now eating McDonald's chicken sandwiches. They decided to not bother with actually cooking any fried chicken. I'm assuming because it's so damn messy, and that one time grandma's bag busted open and the flour got all over her face and she looked like a white woman oh lordy lord! Both are holding the sandwiches in an extremely unnatural fashion, and taking smaller bites than is reasonably possible. The crescendo of this melodrama is when Black Lady 1 says something to the effect of, "Girlfriend, McDonald's has got this chicken in the bag!" and the other echos her comment with a "Mmmm hmmm". You could insert this dialogue into Huckleberry Finn and it'd fit perfectly. I'm surprised they didn't start cutting open a watermelon during this scene and demand reparations for slavery. Their body language makes me think they'll break into gospel songs and start dancing, holding those goddamn sandwiches the whole time. I guess I cannot order one of these sandwiches, as I am not interested in "southern flavor", i.e. acting black, whatever the fuck that means.
