Seriously. I will fight this till I die. There is fiction (not real) and nonfiction (true events). It's easy. (Sparing all the metaphysical arguments about how one determines what is "real")
Creative nonfiction is simply nonfiction written well. You don't need a subcategory for that. That's like saying we need creative photojournalism. It's a pointless subcategory to make people feel special.
And if a nonfiction writer 'only changes some things to fit a greater storyline' that's what I call "bullshit". That's a fictionalization of true events. Calling it creative nonfiction is misleading and wrong.
Rant over.
