I always feel ridiculous being called caucasian. I understand somehow it's come to mean some version of white. But it just makes me think of the Caucuses mountains and how little I can identify with Georgia or wherever.
What possible genetic diversity can be had from just 3 families [0]... (Shem, Ham, Japheth)
I identify most with Inyalowda [1], haha.
I'd prefer to be called German Irish (or some other identifiable family history origin) or American. White or Caucasian isn't a nationality or race.
If your father is from Ireland, but you are dark skinned then you will suffer the same prejudices and abuses as anyone or your skin color. If your father is Kenyan and you are light skinned, you will smoothly fit in with the “white majority” without anyone digging into your history.
The context of US race questions is to counter US racism. Logical etymology doesn’t really apply.
If your ancestors came to America and were Irish, they faced discrimination just as much as other groups, if not more than most, even if they had a similar color tone as other Europeans.
