I understand where this person is coming from, but it also has huge problems.
I grew up a Southerner from the deep, deep South. In many places especially where there are large black populations – as there was and is where I sprouted – BEV and white Southern English overlap significantly.
In other words, when I’d travel outside of the South one or another of my northern relatives would tell me that, “You talk like a black person!”
No, I talk like a white Southerner, dumbass.
Whose culture was I appropriating when I was four? My own? How is that even possible?
(In Seattle, I also got accused of eating “black people food” because after the Southern exodus, things that ALL people eat in the South like catfish and collard greens – which I fucking love – became associated by clueless northern folks with black people.)
