Do rednecks really think anyone buys their bullshit rationalizations about what that flag "means" to them, that it somehow no longer means what it has always meant? Since when do symbols of genocide and brutality and institutionalized cruelty get to magically shuck off their history and start over again? More importantly, why would you want to do that?
The idea that the Traitor Loser flag now just stands for "courage, family, and good times" is just ludicrous. It cannot escape its history so easily, or indeed at all. It is the emblem of the eternally butthurt, of people who take some perverse pride in being descended from people who fought against their own country for the right to own and brutalize other human beings. It is not a point of pride, it is a point of shame.
Slavery and its vile structure is a stain on this nation's soul, one that the Founding Fathers saw and understood, and regrettably did not move to correct quickly enough. But once they finally did move to correct it, the southern states felt more obligated to their disgusting institution than to their country.
They lost, and paid a more than fair price; if anything, in retrospect, the Union clearly didn't finish the job and beat the stupid out of 'em.
Now, while it can no longer stand that public places show open support for this, I really couldn't care less if people choose to fly the rag as individuals. Freedom of speech and all; if people want to tell the world that they're assholes, I encourage them to speak loud and remove all doubt. But by the same token, they should expect their self-serving nonsense to be repudiated by people who have actually watched Selma and 12 Years a Slave, and read the Corner Stone speech, and understand exactly what "states rights" and "heritage" they are referring to.
Ordinarily I root for losers and underdogs, I like rebels and people who tell The Man "fuck you, I won't do what you tell me". But this is just plain pig-headed obstinacy for its own sake. The default excuse for the rapists and killers and vicious oppressors of the good ol' days is that they were people of a different time. They certainly were, and it certainly was a different time, and the best way to ensure that the mores and rationales of that misbegotten era stay in the past is to stop memorializing the schtick and totems of that era. They need to either let go and get rid of the damned rag, or get used to the rest of the world calling them on their bullshit.
