What's really funny in all of this is, that if you took all of the people of Scots descent in the USA, the percentage of them that display any interest in celebrating their Scottish heritage would be miniscule - probably 1% or less. (Don't know about Canada and Australia.)
Kilt-ownership and other manifestations of "playing at being Scots" are actually quite rare, given the vast numbers of Scottish descendents in this country. Most simply don't care and couldn't be bothered. The Scots have simply been here too long to embrace any "hyphenated American" identity, unlike later arrivals like the Irish, Italians, Poles, etc. Who ever hears anything about "Scottish-Americans", or "English-Americans" for that matter? These groups have been on the continent so long they are now simply Americans.
Compare the paltry membership in US "Scottish Societies" to the much more active organizations like the Ancient Order of Hibernians, or the Sons of Italy!

This forum gives a false impression. The people Jock is struggling so hard to understand are quite few and far between....
