I was reading an article on the Southern Poverty Law Center's Hatewatch website when I found the term "Southern Strategy". I looked it up, which then led to the term "Dog Whistle Politics". This is good stuff for studying racism, which we are doing for Social & Political Philosophy as well as Ethics. Please read if you are interested. Essentially, when Nixon, Reagan, Bush I & Bush II say, "State's Rights", Southern people often hear that as, "Keep the federal government from making you interact with black people".
