"Dirty Kanza" is an allusion to a racist slur referring to Native Americans. It's buried in a bit of history, so most people didn't realize the origins. I know many people are sick of "political correctness" changing things, but when you think about it, the name was egregiously offensive. Now that we realize that, it makes sense to move on with a different name that does not dehumanize anyone.
