The civilian versions of the Confederate battle flag flew only over slave states.
The forces who ended slavery fought under the US flag.
The forces who fought to preserve slavery fought under the Confederate battle flag.
The long history of the US flag as a national flag is varied.
The brief history of the Confederate battle flag as a national flag is uniform.
The significance of the Confederate battle flag is ambiguous: it symbolizes both the generally good and brave men who found themselves fighting for an evil cause, and it also symbolizes the evil cause itself.
Anyone who flies it is automatically and inescapably associated with both.

The War of Northern Aggression was not about slavery. It was about states rights!
And, the second War of Northern Aggression will be about states rights!
It must be tough for you to have to share a country with people who celebrate their evil ancestors. How do you manage?
