Almost all supposed Confederate “monuments” are no such thing. They are statues erected to intimidate Black Americans and signal the dominance of whites in former areas of the confederacy after the Civil War, and even well into the middle of the 20th century.
They do not represent heritage. They are not necessary for Americans to remember history. There are no public statues of Nazis in Germany, yet all Germans learn of their role in World War II.
Terra them all down.
