I'm from Arkansas. Heck, I still live here. Little Rock is the WORST for racial discrimination.
I didn't actually read the article very thoroughly but OH SHIT IT'S IN
LITTLE ROCK!
Not the same school, but it's still hilarious.
It's not as bad as Harrison though. There is not a single non-white person living in Harrison. Any minority would probably get run out of town; possibly violently.
Living several thousand miles away, I can't speak for what Harrison is like. However, is the lack of racial diversity the reason why you think it's racist, or do you have personal experience to back up the claim?
I ask because I often see people make the assumption that there is a link between racism and a lack of racial diversity in a town, whereas in my experience, it seems to be the most diverse towns that have the most problems. Maybe it's not like that in the US, but in Britain, overwhelmingly white areas tend not to be racist (except in an "oh wow, that stranger looks exotic!" kind of way); non-whites aren't a part of their life, so they just don't care. It's the cities with large and (this bit is important) segregated ethnic minority groups that have the issues.
