Is this offensive...?

A friend of mines sent me this link the other day, it is a grocery store ad during the month of February. The grocery items on sale are quite stereotypical when you think about food that Black people may eat. Amongst the list are ham hocks, greens, chicken, and catfish. Then you have the typical "poor man meal" ingredients of Bologna and Peanut Butter. Me and my bestfriend were discussing whether or not it was offensive. I didn't see it as offensive, I simply thought that it was ignorant to think stereotypical Black foods were a salute to Black History Month. She on the other had was extremely offended, she agreed that it was offensive and ignorant but she also felt that it was poking fun at Black people's lack of healthy eating and the continually practicing the consumption of the worst parts of the animals. To clarify her point, slaves were giving the scraps of the animals that were deemed "unfit" for the slave master. So the slaves made due and ate those parts, i.e. hamhocks, pig ears, frog legs, etc. What do you think?
