This seems rather familiar to a (relatively) recent thread -
For anyone wanting a quick read-through.
My hot-take on the OP is that “Southern Culture” in and of itself isn’t racist. Because it’s (like a lot of things) too broad a term. Nawlin’s culture, built on French/Acadian cultural hybridization along with a large number of other factors, is different from what you might see in Florida, Mississippi, or Texas, although they’d all arguably be a part of ‘Southern Culture’.
For that matter, many African-Americans in the South take deep pride in the way that their food culture is often the prominent one (even if they are angry that their role in creating it is often ignored).
I will say (as is noted in the other thread and similar threads) that the term Southern Pride is more problematic, in that the vast majority of people who use that term see it as an excuse to white-wash (in more ways than one!) the absolutely racist moments of the past to fit a glorious lost culture.
