I'm not sure what's happened to the Scots. I only really visited and knew lowland scots -- not the highlanders leave alone folks from Skye etc. but to me the Scots seemed, I'm sorry to say, pitiful -- they had the entire William of Wallace bravado on, yet none of them could speak Gaelic. They were very much "I hate the English", yet they only knew English, they were not Christian anymore and seemed not to know their own culture.
it's almost a hollywoodisation of culture
That fits the description of a Scottish Lowlander that I know who immigrated to this country. He has the bravado of William Wallace--he used to walk out of movie theaters when "God Save the Queen" was played at the conclusion of films. However, he's quite aware of his heritage--for example, he often appears at "Burns balls"--commemorating the birthday of Scottish poet Robert Burns--that take place in January within the Scottish-American community, and he reads Burns' poem
Address to the Haggis, one of the highlights of such programs
