In the end, I suspect this is much more about the writer wanting to get out in front on the next cause célèbre and get noticed than it is anything else. What a way to celebrate Memorial Day.
Of course, using the writer's logic, we'll need to change the name of things named after President Lincoln, since he was guilty of many racist attitudes and comments. And let's not forget things named after the various military leaders who slaughtered American Indians - they will need to purge those as well. And, of course, everything named after FDR needs to be looked at since he interned American citizens because of their race and nationality. And I recently read that JFK apparently had a man-crush on Adolf Hitler, so anything named after ol' Jack has gotta go as well.
And then there's the issue with all those buildings and monuments all over America named after the Founding Fathers - many who were slaveholders. Ready the sandblasters.
But it's really not about that. It's really politics and about loathing the Confederacy which, as David Blight has written explains the real motivation behind much of this:
the Confederacy is to this day the greatest conservative resistance to federal authority in American history
Happy Memorial Day - unless, of course, you're a Southerner with Confederate ancestors.
