A person who, being born north of the Mason/Dixon line, has an inflated opinion of himself and his intelligence. He believes that rapid speaking and condescension toward those born south of the Mason/Dixon line entitles him to assume that all such persons have never heard of indoor plumbing, (I actually had a cousin I'd never met before tell me that was one thing which suprised her about Alabama - the indoor plumbing), have never read anything longer than a comic strip, and never date outside the family.
If you, sir, hold no such opinions, then you cannot be called a true Yankee. :-D
A sociology professor told me once IIRC that Southern culture is distinctive because we are made up of comparatively few ethnic groups: Native American, African American, British Isles, and French. There were smatterings of other nationalities who settled here, but most of the Scandinavian, Slavic, and Mediteranian immigrants settled in the industrialized cities of the North.
Don’t forget the Southern Scots, Irish, and Welsh settlers.
I defended this country for 20 years, but because I love the South, I have to put up with the constant assaults on my heritage. So I fight back.
One thing I've found though - trying to teach a Yankee the truth is like trying to teach a pig to sing - its a waste of your time and it annoys the pig.
You’re right largely about the ethnicities in the huge bulk expanse of the South, but here in MD (and part of the Virginia mountains), we have a huge influx of Germans. From the very beginning. And wouldn’t you know many of the latter-day were SOUTHERN Germans, like from Bavaria.
