The only thing disgusting, toxic, and an abomination about the Jefferson Davis memorials is that people seem to think that removing them will change history. History should be remembered so as not to repeat it.
If the memorials make some feel isolated or unwelcome, perhaps that thought is only in their own minds. How will removing memorials from the historic registry change anything? When something important to history bothers you, perhaps it is because you don’t really understand the history. Or, you don’t want to understand. You’ve got your 15 minutes of attention; now leave it alone.
