The various dialects of Scots were pretty much ostracised from the education system for about a century - and the former language of state was dismissed by some as bad or incorrect English . In recent decades it has officially gained some acceptance again but prejudices die hard. The Glaswegian dialect has suffered worse than the older more conservative dialects like my own Borders Scots, or Shetlandic or the Doric of the north-east. Even the prelude to the SND (ie Scottish National Dictionary) dismissed Glaswegian as 'hopelessly corrupt' and refuted that it was even a dialect of Scots at all. In more modern times it is now generally accepted as so.
