I admit the title isn't absolutely fascist, racist, or sexist, but it is some kind of ist, and it is annoying. Maybe accountants, with self congratulatory pride in their profession, feel the urge to divide the world up into neat little categories?
Finally, while I'm delighted that you agree the title isn't absolutely fascist (which you never claimed in the original post and suggest in your response it to be partially), racist or sexist, I'm entirely baffled as to why you felt compelled to post a comment stating it in absolute terms in the first place.
I'm just asking myself why not write about accounting, and let the reader decide what group he or she belongs to. The answer is clearly something like, we need a good title.
