Sounds about right. When I joined the military I met people from Alabama, and even people from other Southern states had nasty things to say about that state. I didn't believe it at first, but then I saw enough over time to realize, "I hate to say it, but maybe they're right. At least about some of the smaller towns and more rural areas."
I met a few nice people from Alabama, yes. I also met... a surprising number of not so nice types. I'm Asian by the way, not White. I'll let people fill in the gaps.
This is not a state specific thing, and it's using a single state as a scapegoat because of this single news story. This kind of shit could happen in rural areas of almost any state. This is a ignorance and racism issue, not a geography issue.
