Racism is part of the reason for the rural/urban split but I tend to think it's more complicated than that. I think religion has more to do with it. Imo, the northeast is far more racist and segregated than Georgia, yet the rural areas in Georgia remain quite conservative, but extremely religious. For example, Jobar's brother, who is very religious voted for Trump. He is not the least bit racist imo. ( Jobar gave me permission to mention this ) Jobar was very upset with his brother as they have always been very close and his brother has said that he despises Trump. Jobar asked him why he voted for Trump. He said he was scared that Biden would be manipulated by socialists.

This is not at all unsusal here. People have fallen for the socialist nonsense that comes from the right. That is why the Republicans are trying to paint Warnock and Ossoff with the socialist brush. I don't know Warnock's exact positions, but I've read Ossoff and they are pretty much in line with Biden, hardly socialist. Racism may be one factor when it comes to the urban/rural split, but as one who lives in a suburban area inside the city limit of a small Black majority city which is at the edge of some very rural areas, I strongly believe that religious extremism has a lot more to do with this than racism does. It's complicated, just like most things are when it comes to humans.
I meant that racial segregation had been the primary driver of political divisions between distressed inner cities and redlined suburbs, and was the driving factor in turning rural America more Republican than it would otherwise be. Both White and non-White Americans tend to be fairly religious. I agree that the Northeast has been a historical hub of that sort of behavior.
Yes. All of my local Black friends are very religious, but they don't mix their religious beliefs with their political beliefs. My closest Black friend has no problem with me being an atheist. That is very different from the type of reaction that I usually get from White evangelicals. I wasn't talking about those who have moderate religious beliefs. They aren't the problem. The problem is that in the rural areas of the South, there is a lot of religious extremism. These folks seem to think that allowing same sex marriage, giving women reproductive rights, forbidding discrimination in regards to trans folks etc. is an attack on them. That is a bigger problem, at least where I live, compared to racism. Those beliefs come directly from their religious beliefs. Sure, there are some Black evangelicals who are just as extreme, but for the most part, they seem to respect the SCS.
As I've already mentioned, these same people are scared of the word socialism, which imo, is why the two Republicans are using that word in most of their attacks against the two Democrats. I guess they equate socialism with some scary attack by the godless on their religion, despite the fact that a lot of the words attributed to Jesus seem pretty similar to socialism. The problem is that there are a lot of people who are simply clueless. You probably already know that.
Btw, our neighborhoods here are far more racially integrated than any place I've ever lived. Socioeconomic segregation is still a problem, but even that is not as bad as it is in the northeast.
