The confederate flag. Symbol of southern heritage or Hate?

how can you have one without the other? The heritage of the south is buying slaves and using them to tend their crops. It’s what their entire economy was based on. So much so that they resorted to seceding from the union and taking up arms against the United States to keep their slaves. Slaves that were beaten, tortured, and killed at will. Thinking upon that time with a sense of nostalgia would be akin to people flying swastikas in German to commemorate that time in their history. It disgusts me.
