Nothing wrong with being Polish Scotslass!
I'm often accused of being a Brit in the U.S., and English in Oz (as I don't have a strong Australian accent).
An English guy I know identifies as British unless someone asks him why he isn't taking the day off for St Patricks' Day. Then he says "I'm not a "Paddy", I'm ENGLISH". (in a puffed up kinda way).
