A couple of notes:
1. This is north Mississippi. While I am making no claims that southern Mississippi is any less conservative (it is not; if anything, the reverse is the case), it is less poor (YAY GAMBLING). So you get fewer people walking around with no teeth in their head.
2. Most people would point out themselves and use that as a proof by contradiction of someones attempt to paint a state by a broad brush. I will not. In any system, there are outliers. In a state where 90% of whites are Republicans and 98% of people are Christians, sometimes, there are Democratic atheists. Sometimes there are socialist atheists. Perhaps the 50% least redneckish of Mississippians are not represented here. But am I willing to say that this is unrepresentative of the 50% most redneckish? No, I am not. Even if it were just representative of the 1/3 most redneckish, which I think would be a quite reasonable claim, well, you would still walk into people like them far far more often than people like me.
3. Now, maybe that's a good thing. I can't imagine what a state composed 1/3 of overly entitled, lazy, snobbish, liberal, atheist, white, young, male computer science majors would look like. Certainly it couldn't last for long. Mississippi, on the other hand, has endured for quite sometime. So maybe there is something to be said of rednecks?
4. There isn't.
