Here's my 2 bob's worth: I consider myself a Scot. I was born in Aberdeen, but emigrated to Australia when I was two. Everything I've formally learned, earned, or aquired came from Australia, right down to the accent (unless I've had a tad too much speyside!). I've fought & bled for Australia & celebrate her national days with pride. I consider myself to be an Aussie patriot, & am proud to be considered Australian by others. I would lay down my life for Australia without hesitation as both the country & it's people have been good to me, so to a large amount I also consider myself an Aussie. At the same time however:

I was born a Scot. I was raised a Scot at home. Although I tried to hide it for a long time (imagine how traumatic it was being made to wear a kilt on your first day of school!), ultimately the blood will out. Both my Great-grandfather & my Grandfather fought in the same Highland Regiment. Culturally at home we lived as Scots. I have no wish to appear rude or insensitive here, but this example seems a reasonable comparison for those born elsewhere of Scots descent: Does a Jew feel less Jewish because they dont live or originate from Israel? The Diaspora happened, & as a result Jews may be found all over the world, proud & united in their culture & heritage. Likewise, the Clearances happened, & the Scots too have found their way all over the world, where they have made significant cultural impact in their adopted lands. Are their descendents less of a Scot? I personally dont believe so.
