But, he was right about one thing. "Scottish" is not a race. It is however, an ETHNICITY, which is, interestingly, NOT limited by geography. FWIW, one also does NOT have to have genetic ancestry in an ethnicity in order to adopt it as one's own.

One can become, at least partially, Scottish by adopting elements of the culture as your own, regardless of where your parents came from.
