I think Folkman meant Scotch people, meaning people full of Scotch.(whisky) Morticia:>)
As for being unfriendly, I don't think we are. Superior to the Irish.....not true..Celtic family. Subservient to the English???? LOL...eh no just defensive to the few of them that say things like "the Scots are mean and don't buy drinks".......strange statement there, how can they know that...has an extensive Scottish pub crawl been carried out to reach that conclusion?? Broad statements regarding people are generally made though an ignorance of that particular race. Stereotyping sucks! In fact that would be my answer to the question. What's the most unfriendly folk....Folk that stereotype other folk.
