I grew up in East Texas (think Old South) during segregation. There were some rednecks who hated blacks with a passion, but most middle and upper class whites had friendly relationships with blacks. There was always the socially mandated distinction of not dining together or social separation by race, but many had close personal friendships that transcended that to the point of being almost family. (This may have dated from slavery and the paternalistic relationships of owner and servant.) Nevertheless, there was no widespread animosity in my part of the country.
Texas is neither southern nor western. Texas is Texas.
