"…Accusing all whites who take pride in their Southern heritage of being "white nationalists" or "hatemongers" is itself both non-sensical and inflammatory. "

Please do explain what aspects of "Southern heritage" you're talking about? The subjugation of black Afro-Americans is the very basis of that heritage and what allowed some in the South to prosper. Any Southerner who doesn't take that into account is avoiding the truth. Present-day Germans are, for the most part, able to deal with a reprehensible history so why not Southern Americans?
