Do you know what the Confederate flag meant before it was co-opted by the 1920's Ku Klux Klan? Do you know what it still means to Soutpeople today (not the Ku Klux Klan)?
Did you know the original Ku Klux Klan was a peaceful, men's fraternal organization (1860-1870) as a way to cheer up the families of the defeated South? It was disbanded when unscrupulous men donned the Klan robes and committed lawless acts. But this did not stop these lawless individuals.
What is interesting is during the birth of the KKK the confederate flag was NOT used as a symbol. Even today that do not accept the flag as their main symbol. A blood dripped cross is. Is a cross racist? They also use the bible. Is the bible racist? Or are these sick misinterpretations?
A few more factoids.
The Confederate Flag was never the official flag of the confederacy. It actually became more prominent after the war ended.
The flag actually became seen as racist during the civil rights movement. Not the civil war.
The war was fought on a false premise and, given time, slavery would have disappeared from the South in another generation. It was already waning, because of industrialization. Had the North not been secretly fearful of the South's innovation, trade inroads, and business acumen that was outstripping the performance of the northern industrialists, the war would have never happened.
