I think this is such a reductive take of The South. A great tool for understanding a culture is sometimes to place it historically so you can be more objective. For one, The South has more black people and poor than anywhere else in the country, meanwhile liberal states like Oregon, Vermont, and so on are some of the whitest, so the theory that it’s about lack of contact is obviously lacking.
The South places strong emphasis on self-reliance and community, to a degree other areas might consider to a fault. That manifests in wanting smaller government, less outside intervention, close-knit communities and neighbor friendliness, and so on. Someone “whining about how hard life is and begging for handouts” (said by someone from The South) is in their eyes selfishly draining their community because of their lack of self reliance.
To an extent: this is true. The South is relatively poor so they know better than most - there are many people who would rather get handouts than make better decisions. This is also wrong in many cases: many people are poor systematically, and are in a rut where self reliance isn’t enough. There’s tons of complexity to these things that both sides paint black and white.
The South isn’t your culture but mean, like some seem to think. It’s a different culture in many ways. One where pride, self reliance, and community are really important. If you want to have a chance at solving some of these problems and answering these questions you should be aware of this.
The South doesn't get points for that while lobbying to destroy people based on stereotypes it imagines.
The strongest opinions on any group are always from those with the least contact with them.
