Sounds to me you are describing the same thing as him, just you personally happen to want to buck the social norm so you live in a different oil bubble than most of your race.
If every day the bus was full of multiple races including white and your job was full of multiple races including white, you would actually describe what you think is happening.
At my place of work, about 1/2 the employees are white, about 1/4 are Hispanic (mostly Mexican, but a few from further south), about 1/8 are black and about 1/8 is from somewhere else (mostly the Marshall Islands or China). Everyone gets along pretty good without any racial divides. All in a part of the country that, if most think of it at all, most think of as utterly lily white.
