the gist of the argument amounts to the following, that vernaculars, patois, slangs, dialects, gutter-languages etc. might well have a place in the realms of comedy (and the frequent references to Billy Connolly or Rab C. Nesbitt substantiate this) but they are inferior linguistic forms and have no place in literature. And a priori any writer who engages in the use of such so-called language is not really engaged in literature at all.
