That graphic cracks me up.
But seriously, would people care, or even NOTICE, the ethnicity of someone else if they shared the same culture and values?
There was a family in a German heritage small midwestern town that adopted a black baby girl and raised her in the community. She grew up, was raised in the same culture as everyone else, went through high school - and seriously, people didn’t even notice that she was black - to the point of being embarrassed sometimes.
