I can’t listen to it right now, but the issue with characters like Aunt Jemima is that they were just racist stereotypes given a name and slapped on a box.
I think a good analogy for this situation would be a themed chain where an AI pretends to be a comedic racist caricature.
I don’t know about stigma, but the whole family is just vaguely dysfunctional. We can’t really spend any time together for more than a couple of hours before someone starts a fight, generally (but not always) on accident.
