You stated that people in suburbs and inner cities are much more racist. I doubt white people in suburbs or inner cities are more racist than conservatives in rural areas.
You want me to show factual data that supports how some people in certain areas may have never seen a black person or a hispanic person before?
I actually believe it's the wealthy whites within urban or semi-urban enclaves who are probably the most racist of all, since they control and engineer the policies in question (while cleverly blaming it all on "rural whites" who are impoverished and powerless to have any influence at all). They may even identify as "liberal," so they know how to play the game and say all the politically correct things (while quick to condemn those who say politically incorrect things). They live in insular, gated communities to protect themselves from the "riff raff" out there. They see minorities in more abstract terms, either as "faithful servants" or symbols of oppression (which is/was caused only by rural whites, not the sophisticated urbanites who are "progressive" and "liberal").
I think they're actually closet racists who are so afraid of being found out that they end up accusing everyone around them of being racists. (This might also apply to a few members in this forum.) They're also irredeemable capitalists who have gained their wealth by exploiting minorities in the US, as well as countless millions of others in the developing world by their shameless embrace of globalism and free trade. But because they verbally attack impoverished hillbillies in West Virginia, they actually believe they can face the world with a clear conscience and that everyone should praise them for their "enlightened" views. They're not fooling anyone but themselves.
Rural whites are not as insular as you might think, at least in terms of seeing black and Hispanic people, since there are plenty of rural blacks and Hispanics as well. In fact, it's kind of uncanny, when I see rural whites, blacks, and Hispanics, I observe that they are soooo much more alike than they are different. It's mainly in the cities where there are sharper contrasts between lifestyle and culture in different neighborhoods. There's greater tension, anger, and class resentment emanating from the so-called "ghetto" neighborhoods versus the wealthier, upscale, gentrified neighborhoods. The income gaps and extreme contrasts between rich and poor are far more prevalent in urban America than what you'd see in rural areas. Blacks, whites, and Hispanics in rural areas have approximately the same level of standard of living - and they're all equally screwed by the rich whites in the cities.
