Americans and their nationalities?

[AFTT47]

I am an American by place of birth and citizenship. My mother was the child of two Portuguese immigrants, my father of Irish immigrants. My heritage means nothing to me, nor does my nationality other than for practical purposes.

The older I get, the less use I have for anything tribal. I sure as hell don't self-identify by any of it. I might call myself a nerd, a space enthusiast or a Star Trek fan but never American, part Irish, part Portuguese or Caucasian.
