Where I was a kid everybody was of Scandinavian descent. I never met a person of color, except a few Hispanic migrant worker's kids, until I was in my twenties. Fort Lewis WA, working for the Army.
I was certain that I wouldn't be accepted and I was surprised when no one seemed to notice I was White!
I am comfortable with a wide mix of people and the only social environments I'm uncomfortable in are with people of any color who are emotionally unhealthy.
