The CSA battle flag was not an issue until unhinged Leftists made it an issue. Dollars to donuts says one could fly the actual CSA flag, and these ignorant Leftists would not even recognize it. For that matter I doubt they could correctly identify the century in which the Civil War occurred.
Well, duh. The state flag of Georgia is directly taken from the first national flag of the Confederacy, yet few say a thing about it. Even during that weird media-manufactured Confederate flag hysteria back in mid-2015, almost no one said a thing about Georgia's flag.
