I don't think that Doric Scots is one bit discredited. It is a great tradition. And has nothing that I can see in common with "Gaelic." Nor do I see anything wrong with Harry Lauder. Or music hall comics. I like a lot of their stuff. So far as I can see, what really discedits Gaelic is the repetitious, monotonous dance tunes that are so popular, and so damn boring.
