It's better than it used to be. When I was in elementary school I heard the "War of Northern Aggression" as an alternative name. But by the time we were covering history in middle and high school no one called it that.
I think you'd maybe still find some teachers saying that in the most rural parts of the state, but it's definently lessened.
However, things are getting worse in other ways. Wouldn't be surprised if they start bringing back Jim Crow
