I'm from Alabama and if we were to rename the state on a historical figure I would suggest Rosa Parks over Dr. King. But I fear the chosen name is an attempt at humor at the expense of the white people of the state. Which is unfair to them and to most especially Dr. King.
It's an attempt at humor that's an over-generalization. It suggests that for those of us from Alabama who would have gladly marched with Dr. King or stood with Rosa Parks, had we been alive to have done so, are to be lumped in with the racist history of the state simply because of the color of our skin.
But that's my opinion, you have your opinion, and I respect that.
