Here where I live in California there was a truck that used to drive around with a confederate flag, but I haven't see it since the shooting in Charleston. There are plenty of people who embrace the confederacy even though they are nowhere near the south and have no connection to it.
There are reasonable places for Confederate flags.
Civil War re-enactments.
Honoring the dead of the Civil War.
Cinematic and educational purposes. (as in Germany it will be difficult to see images of prominent Nazis without the cross-of-Satan armband during the war or images of Nazi Germany or the pre-1933 Nazi Party without you-know-what flag).
Mockery.
Otherwise the Stars and Bars has become a symbol of KKK fascism. It is now largely a flag of disgrace along with Commie, Ba'athist, and ISIS flags.
