It's just a convenient and, hopefully, inoffensive way of pigeonholing whatever social or ethnic groups are deemed worthy of special categories by a society. Red, yellow, brown, black, white... its a social rainbow.:rainbow1:
Personally I used to be white when I lived in Baltimore, but now I've moved to the Southwest I've become "Anglo."
I'm waiting for 'beige' to catch on...
It doesn't make sense to call all "white" people "Anglo". The Anglos were one tribe among many in one region in one linguistic/ethnic group in Europe. There are plenty of fair skinned people who aren't Anglo.
