A little background
On June 17th of this year, a domestic terrorist walked into an evening church service in Charleston, South Carolina. After an hour of listening to Americans discuss their devotion to God, he opened fire on the room. Nine people died.
He chose one victim to spare and tell others of his motivation (five others survived). The white, 21-year-old man explicitly stated that he was killing black Americans to start a race war. Photos later surfaced of him bearing the flags of apartheid states, citing quotes from the founder of The American Nazi Party, burning the American flag, and--of course--waving a Confederate flag.
It's that flag that's become this tragedy's Easy Way to Preventing the Next One (TM). We always find something to blame and kick weakly in the shins after a white guy kills a handful of folks, but for once the target is a reasonable one. Making the Confederate flag a less common sight won't change the pervasive racism and cultural cowardice that filled this shitbag with the idea that murdering people would make him vaguely fuckable to women.
And some of that has spread further, to a desire to take down statues of Confederate generals which we apparently have aplenty down here. As a Southerner and a veteran of the US armed forces, screw The Confederacy. Screw their flag. Screw their generals. Screw each and every article of Confederate iconography.
But not the horses they rode in on; I don't think Traveller was racist.
