Rasism isn't exactly what we think it is. You could say a slur not meaning what you said. For example if i call someone from india a "raghead" its a acial slur bc it's to offend them. From the civil war we have seen the Confederate flag, also known as the Rebel flag. People today say that is a form of racism, which it is not, it actually represents peace. Way back people, besides white men, was used as slaves bc of there skin tone. We have also seen tv shows took off of tv bc of that flag, such as the dukes of hazzard.
