Alright fellas this just gave me a horrifying thought. Let's say that Carolina took Korea (unlikely, but hilarious). Then, let's say that Charlotte and Philly give the Koreans "Lost Jew" status because OTL Imperial Japan ran with the idea that Korea and Japan were of the same race and had the same progenitor to make administration easier. After all, you can still hate the Chinese, Indochinese, etc.
Theoretically, if this series of events occurs, I could be born in the Madnessverse. Granted, my grandpa and dad were/are Yankees (Marylanders) but it could happen. Which is utterly horrifying to think about.
Also, Chapel Hill has a Korean fried chicken joint IRL. I've eaten there, and it's absolutely delicious. I would also propose pulled pork sandwiches with kimchi (it would basically be a spicy BBQ sandwich) and bulgolgi sandwiches with coleslaw. There are a surprising number of ways that a Carolina-Korean culture could work.
