Who counts as a "Southerner"?

Indeed, states are not 100% homogenous and uniform in their populations and culture. Any state, with hundreds of thousands or millions of residents, is going to have at least a few people of nearly every type. Frankly, though, that is a banal and irrelevant observation. The fact still remains that some states have a history in modern times and living memory of pushing toward progress and others have a track record of resisting it. The vast majority of white Mississippians seem hellbent on fighting tooth and nail against modernity; but then they whine that they are being “stereotyped” when anyone else points this out. Can’t have it both ways, guys.
