Certified brown person here. The only thing I think about in terms of deciding where to stop is how far I can get before needing gas, and what the odds of finding decent food are. I've travelled in rural areas all over the country: midwest (my wife grew up in rural iowa), west coast (wife's family is from the rural oregon coast), and south (worked a summer in southern virginia, my best friend lived in south georgia for a decade). I just got back from a road trip through rural Utah, Idaho, and Wyoming with my white wife, mixed kids, and Latina au pair. In all this time nobody has even looked at me sideways.
Hell, the precinct where I live went for Trump 58-34 in 2016 (the year I moved here). The precinct a few minutes away where my parents live was 57-32. Most of the ones around us were 60-30. Again, no problems.
I have to agree with the sibling comment. I have no idea how these folks would perform on an IAT (and I don't care because they're bad science: https://qz.com/1144504/the-world-is-relying-on-a-flawed-psyc...). Southerners are nice to visitors and keep their thoughts to themselves for the most part. I'd rather deal with that than west coast frigidity or NYC aggressiveness.
As someone who recently made the jump to a rural area, these problems are almost entirely imaginary. The notion of backwards, ignorant, racist rednecks occupying all the rural lands is nothing but a bigoted stereotype.
Southern hospitality is real; and while rural peoples will be more likely to notice and acknowledge cultural differences, they generally are open minded and just as respectful of nonwhite neighbors as white ones. It's the city folk who don't understand the roles that politeness and respect play in southern living, necessary for the unbelievably high trust society that only really exists outside of cities.
The truth is that urbanites have been hypersensitized to so called racism, and completely mislead as to what rural/conservative culture is actually like. But I don't mind a bit, that means more cheap land for me.
Appalachian culture is extremely insular, even with respect to other white people. I once had a conversation with a (white) guy who had married into a family in Appalachian Kentucky. Folks in town regarded him as an outsider even after a decade of living there.
Culture has changed somewhat since then. I don't presume to speak for anyone's experience but my own, and I go off of the stories that my friends have told me for other things.
That said, Trump flags fly everywhere, and BLM flags get torn down/burned/vandalized. I don't think its really fair to say that its all politeness and mutual respect - in my experience that is how it is until you accidently fall into one of the cultural battlegrounds, and then its more conform or die. Lastly..

I think this can be true while the rest can also be true.
I suppose you could say that ruralites are more tolerant of intolerance in general, even when they individually may be welcoming. No argument about the flags around here...but I get the impression that, at least where I've settled, even if you're a little different, if you stick to your property and don't make waves nobody is likely to mess with you...and to be honest I kind of appreciate that sort of live and let live attitude, even if it requires some degree of conformity.
As far as I can tell, a somewhat rigid common culture is sort of the price of high trust living, where you can leave your doors unlocked and your keys on the porch. That doesn't justify violence against minorities/lgbt of course but... there's always the city for that I suppose. It's definitely a very different non-pc attitude around here. I certainly understand why a guy like Trump is so popular in these parts.
I think there's also an element of cultural mismatch. Trevor Noah has a great passage in his autobiography about how he could cross the intense inter-tribal antipathies in South Africa by speaking another tribe's language: https://www.josephineelia.com/power-of-language. Rural places in America are like places everywhere else in the world--you have to "speak the language" of the people in the place where you are. If you go to rural France and conspicuously don't speak French, you'll face hostility. Obviously in America we speak English everywhere, but if your mannerisms and attitudes give you away as an outsider, you might not get the same warm reaction as someone who knows the cultural cues.
Living in a place with no amenities, an extremely regressive/borderline extreme social climate and a lack of economic opportunity for people who don’t have remote tech jobs and it gets depressing really fast. Also when you try to buy healthy food from a dollar general.
