Mr Abernathy, dog whistles in this context are not something dreamed up by the left. Lee Atwater, Republican strategist to Nixon, Reagan et al., explicitly admitted that "states' rights," "law and order," and other such phrases were seized upon by every R candidate after Wallace once it became clear in about 1968 that you couldn't go around saying (his words), "nigger, nigger, nigger." At the end of his life, Atwater realized his work creating these dog whistles had coarsened the public discourse and made racism among Republicans more hidden and yet simultaneously prevalent, and he repented of his folly. You are incorrect to now foist this myth onto the left.
