With Emacs, Webster's 1913 calls the shots to a far greater extent than
that does:

   1. The act of differing; the state or measure of being
      different or unlike; distinction; dissimilarity;
      unlikeness; variation; as, a difference of quality in
      paper; a difference in degrees of heat, or of light; what
      is the difference between the innocent and the guilty?
      [1913 Webster]

The difference between the innocent and the guilty is the culpability of
the latter.

   (cl-set-difference '(innocent) '(innocent culpable))

Yes, I do: I've written much Emacs Lisp over the years.

Sure, if that's your preferred sobriquet for the customary practice as
regards the creation of linked lists.
