It's my belief that the more recent ( say, last 75 years)general discreditation of scots gaelic, doric scots, "braid" scots and other scottish pronunciations of english, in all their various dialects and variations, can be laid firmly at the door of the music-hall comics like Harry Lauder and Will Fyfe. Their stage, sound and screen characters played up to the common misconceptions of the scots as drunken, miserly buffoons, and used their languages to do it. This reinforced the attitude that the scot, speaking his own tongue, was to be ridiculed and could be regarded as a laughing stock, purely because of his speech.

All these popular beliefs were, and are today, simply part and parcel of the disdain in which the english held the scots, the like of which was made very evident at the time of the Union of the Parliaments, and which has been encouraged by authority ever since. It was a long-time deliberate policy of the government, from the early 18th century, to destroy and root out the use of all the tongues which were not "normal" english, and in my schooldays, it was still normal for a teacher to punish a child who made the mistake of using a scottish word in class, although the same teacher would wax lyrical over the same word when reading poetry by Burns.

All that having been said, I enjoy the sound and the "taste" of all the scots dialects (even if I don't understand some of them!) None more so than the lilting gaelic, which I believe may be making a come-back partly at least to the resurgence of interest in the Irish language, and all the associated "celtic-ness" associated with it. If the rise of popularity of the Irish gaelic helps revive positive interest in the scots as well, then I'd say it was a good thing, even if it did nothing else except make money for the Corrs!
