But this isn't what you said. You said "not all writers produce novels--nonfiction, short stories, plays, and journalism are all real writing." Now, when I point out that no one in this thread said they're not, you change your tune--now it's "not all writers produce stories" you claim you said.

I don't see anything in "stories are always popping in their heads" that privileges novelists over writers of short fiction or plays--or nonfiction and news either. Because it's the gift of writers to recognize stories where other people hear "blahblahblah who cares?" Hell, even a lot of technical writing involves casting whatever has to be conveyed in the form of a narrative, because that's a primary way we have of making sense of our world.
