I grew up in a small state called New Hampshire and some of the locals there call it...
Ne Hampsha.
I grew up on 26 acres in a house my dad built, with two big fields and we were surrounded by woods.
There were a lot of cows and farms nearby.
There people use the term "rednecks" or "hicks" to refer to local people in the countryside that often: drive around in big jacked up trucks, chew tobacco, shoot guns, drink canned beer, and wear steel toed boots.
These people are not particularly educated or worldly.
They have a regional mindset that doesn't extend beyond the limits of their town or area. Their mindset is conventional, traditional, conservative, local and ignorant. If you are different then you are subject to ridicule as they aren't open to new ideas and experiences.
However, I have realized through all my travels that these kinds of people exist all over.
At least in most places that I have been to or lived in. It's a mindset that fears outsiders and something different than the status quo.
For example, in Taiwan they may wear a different mask (not the kind to protect you from germs, but they wear those too).
There they wouldn't be chewing tobacco, but they might be chewing betel nut instead. They don't drive big trucks, but they might be driving a scooter that's been souped-up and that has a muffler that is extra loud.
Rednecks do not typically have the best manners either.
In China, you may find "rednecks" spitting and hawking frequently on the street or even staring at you. You might even see a "redneck" in China do a "farmer's blow".
The funny thing is that in China a large percentage of the huge populations found in cities like Shanghai or Beijing contain Chinese from the countryside or much smaller cities. Many people, not only in China, are moving to the city in search of a better life.
So even if you are not living in a big city chances are you are going to run into a redneck of sorts. A person who has had little exposure to things, ideas and people outside of their native region. They're people who are living in a smaller bubble.
Travel and the experience of living abroad amongst people of different cultures does make ones world view and bubble larger.
It's impossible to know and be aware of everything.
We all live in a bubble of some size or kind.
I suppose the term redneck or rather ignorance doesn't just refer to people from the countryside. It's an urban phenomenon too and I also meet so called "educated" people who are ignorant.
