Statues are usually made to honor or commemorate a person/event. By making a confederate statue, one is honoring the confederacy; that would mean that that person is also honoring the fight to keep slavery. Slavery is absolutely NOT something that should be honored. In the present day, Black people, as well as POCs in general, have the same rights as you and me. However, they still face racism, and keeping confederate statues does nothing to help that; if anything, they show support for racism. All confederate statues should be taken down.
(Just IMO, you don’t need to write this, having a confederate flag is almost as bad as having a swastika honestly. Both are supporting horrid events.)
