Here in the United States, they never ask you your ethnicity because it could be used for discrimination.
Heh, not in the South. I have to fill in my ethnicity in for everything
. Sometimes I bubble the "Other" spot it and write in "European American" or "White" instead of bubbling in "Caucasian." I'm not, nor have I ever been to, the Caucus.
But, that is not ethnicity. That is race. When I need to fill a form under ethnicity I write Slovak, I don't write Caucasian or more precisely Alpinid (a sub-race).
Thank God you don't. Concepts like that go hand in hand with scientific racism and craniology. I agree that in Europe these things are luckily less important than ethnicity, or culture if you like that term better.
Which reminds me of that quote by Blumenbach somewhere around the year 1800
Johann Friedrich Blumenbach wrote:
Caucasian variety - I have taken the name of this variety from Mount Caucasus, both because its neighborhood, and especially its southern slope, produces the most beautiful race of men...
He was the one who invented the terms "Caucasian" and "Alpinid", among many others. Knowing this I think I'd prefer to be called Slovak over Caucasian as well.
