I do agree that the South gets unfairly stereotyped. Places like Chicago are much worse in my experience. However the poster who wrote that he never heard a person from the South use the N word must not have been around in the sixties. I heard it plenty from people from the South in those days.
Ive traveled the nation throughout my career. Twice to LA so far this year. I have been surprised at some of the things people say but that is not exclusive to LA. No area has the monopoly on ignorant people.
I have worked with plenty good blacks, Koreans, Latinos, Chinese, and whites from LA too.
Over 30 years of travel, I would put LA area near the top. I didnt just come up with that.
