There are millions (probably tens of millions) of rural Southerners. Many don't want you dead, but vote red because they don't feel accommodated. Many vote blue.
Moreover, when somebody grows up around people who hate a certain group, it's human nature that they'll also develop hatred. What do you do with those people?
I believe the best you can do if pacify them, and convert those whose hatred isn't ingrained. Acknowledging people and accepting the non-hatred parts of their culture is an easy way to reduce the motivation to kill you, and convert those on the fence, without giving leverage. Funding is another way, and while it can give leverage (because adversarial groups shift their own funding towards aggression), I believe if done carefully, the decrease in hatred will outweigh the increase in power, making aggressive efforts overall less effective.
