The biggest diss I have on emacs users, as a vim user, is that emacs is the only text editor where people routinely need to keep a book about it on their desk!
I used to work with a bunch of emacs guys and they all had an emacs book or two on their desk or as a monitor stand. They usually also had one on awk and/or Perl to go with it.
I’m sure they’d probably make fun of me for being unable to edit a file with anything but my specific vim config, which is not compatible with any other human’s vim config.
(I would never seriously judge someone on their editor, but I will bust an emacs users chops and accept a good natured jab back)
