I live in a town that is about as far as you can get from the Confederacy in the contiguous 48 states. The town was founded by Union veterans. But an SCV group from another city has started flying the Confederate flag in a very prominent location in our town.
I suspect that a lot of the backers are not really celebrating their "heritage" but have attitudes similar to yours. Since I'm pretty sure that 99% of the local folk do not favor either slavery or a race war, the flag really doesn't belong here. But no doubt that's another motivating factor for the people who put it up.
I don’t think its about “white resistance” and I resent these racists using an historical American flag.
If they want a “white resistance” type flag, I have a suggestion - get a red flag with a large white circle and a swastika in black in the middle and use that because that’s the kind of vermin they are. And they should keep their filthy racist fingers off a piece of American history.
