Interestingly, most of the "poorly educated white folks" aren't actually poor or working class but upper middle-class or rich--look at Donald Trump--a bachelor's degree in real estate. 
Actually, I'll bet these philistines are most disliked by other white people. Poverty is an education in itself. It's the privileged that live in their homogenous neighborhoods and enclaves that are the most racist. Many whites choose self-segregate and so lack experience with groups outside of their own. That's why they're so handicapped, mentally that is.
