I am pretty sure they know that flag is a symbol, and it isn't a good one.
When nine people die in a mass murder, with evidence left behind that the person responsible liked to wave the Confederate flag around and the same flag is waving next to the states capitol, you don't need any more evidence to know the stubborn worship of that flag and what it stands for is ignorant and insensitive. I don't care if Uncle Jeb was a damn general in the Confederate army. He fought on the wrong side, get over it.
That's the problem right there. The war is still going on in their minds. If you look at the amount of police shootings of unarmed African-American people, it sure looks like they might be onto something.
The Confederate flag is in peoples living rooms and in movie theaters. It's like Dixieland is La La Land, completely devoid of the reality that; "It is no accident that Confederate symbols have been the mainstay of white supremacist organizations, from the Ku Klux Klan to the skinheads. They did not appropriate the Confederate battle flag simply because it was pretty."
and "The Confederate flag, we are told, represents heritage, not hate. But why should we celebrate a heritage grounded in hate, a heritage whose self-avowed reason for existence was the exploitation and debasement of a sizeable segment of its population?*
You can't separate the flag from the hate, however, everyone seems to turn a blind eye to the real meaning of that flag and the gun problem we have in this bipolar country. Everything is spin. Like Rick Perry's accidental accident comment.
I doubt anything will happen when it comes to Confederate flags or guns. There's just too many of them and too few people with the will or just plain common sense to change. So we are stuck with the reality that more people will die in schools and now churches or at the hands of out of control police. America, home of the fearful and the free to fire away.
