The perfect summary of much of modern political discourse.
If someone is arguing against a generally well understood fact -- like, saying that North Korea is richer than the US -- it's on them to support it. They're not doing that here, because the facts aren't on their side.
> I can provide the data if this is an earnest request
It is, please do so we can discuss the actual data as you've said.
Here is the USDA Economic Research Service on rural vs. urban educational attainment and median income; rural areas indeed are less educated and lower income[1]. This Pew Research study shows that rural areas are more conservative than urban areas across a wide range of political issues[2]. Data on religion was slightly harder to find, but this Gallup poll shows rural areas in the US are more religious than urban areas[3]. If any of these results are surprising, I'd guess that you may not have much experience of urban areas as a comparison. To be clear, I still prefer living in a rural area, but I recognize that there are pros, cons, and individual differences.
