Is the Confederate flag a symbol of state's rights or slavery?

do states rights trump human rights? the nazis commited genocide yet i see only a few idiots proudly brandishing that standard. the japanese also committed war time crimes yet there isn't much of a japanese wwii movement. so here we have a bunch of southerners defending their ancestors and honoring their fight to keep my ancestors slaves and to perpetuate 400 years of brutality, , and torture. i consider the rebel flag to be the standard of stupidity...the banner of bushwackers and traitors. the fleur-d-failure . wave it proudly now!
