As a history major, I agree with those who feel that it's a travesty when people try to reshape history to fit their agenda. And I agree with those who recognize that we have seen an increasing amount of that trend recently. Although to be fair, sometimes misconception interferes with the reality or the intent of a situation.
For example: I do not have a problem with taking down statues of Confederate generals from the Civil War. I do not believe that removing Confederate statues is erasing history any more than it would be if Germany removed statues of Hitler or Italy removed statues of Mussolini. No one is ever going to forget the evil that those men did, so removing their monuments is perfectly fine by me.
In a like manner, our country is going through a period of self-awareness. We are beginning to realize that some of the people whom we have immortalized in stone are - in fact - traitors, and as such they do not deserve high-placed positions of esteem within our society.
However, because these people were part of our history, we can remove monuments to their memory from our public squares and move them to museums, where they can still be remembered for being traitors to the republic without glorifying their existence.
UPDATE: This post is one of several that I had written that I later discovered had never been set to "public."
