(Elvis is also from Mississippi, btw)
The KKK was founded in Pulaski, TN, which is about an hour from where I was raised. It wasn't until July, 2021 that the bust of the founder of the KKK (Nathan Bedford Forrest) was removed from the state capitol building. It's now been relocated to the 'TN State Museum' which was magically opened mere days after the bust was removed.
I could provide countless more examples of things I have heard, read, and witnessed, but I am certain you do not need any more examples, and honestly, even thinking about it all really depresses me.
