Er... well without getting too political I think it is probably safe to say the general perception of Ulster Presbyterians is decidedly more mixed in Ireland than that of the Scots Irish in America. Granted much of that is down to 19th/20th century (so post dating the emigration wave) but even before that the Plantations cast a long shadow over Irish history.
I would only naturally presume. Hence I vaguely hinted at that with "different locations wield different results." Although I realize that I had a spelling/word mistake there and wield should have been yield! LOL.
Yes, it is something I was only vaguely familiar with myself, as you say they were never a large community here!
I honestly didn't know until you linked that, that Quakers were in Ireland! See, I'm writing an AAR imparting historical knowledge to the readers while including what's going on in a game, but the readers are also imparting knowledge to me! It's true, we all grow in knowledge together!
Speaking as someone who grew up in the American South and is a bona fide Southern Appalachian Mongrel with a little bit of Scots-Irish somewhere in me, I can vouch that classical Borderer norms and practices still influence a great deal of Southern culture, though often in subtle or unexpected ways. Of course, often "Southern values" are more honored in the breach or by way of nostalgia, but the ideas are still paid lip-service to at least.
I sometimes feel so "isolated" at times, not just because of what I'm doing for "a life", but just because I'm not "American" in the sense I don't fall into any group that "left a mark" and became adopted Americans as it were. But all my studies and inherent romanticism makes me want to cry that America has lost the knowledge of its own heritage and culture. Not that it's a culture(s) or tradition(s) I belong to or anything, but, well, I suppose my philosophical and historical studies are to blame for that. You can say I feel like a stranger in a strange land.
You must have read Shelby Foote growing up or in college? Be still my heart and soul!
