In my job, customers routinely call me and discuss the service they received. It is a mostly white profession, but we do have one black (African American) under my employ.
When a customer calls for a complaint, compliment, or a neutral inquiry, I will often ask them who their technician was. They will describe eye color, hair color, height, weight, facial hair, etc.
If I still am not sure I ask, “Was he a black guy or white guy?”
If it was the black guy, they immediately chime in “The black guy!” and most go on to say something like “I didn’t want to mention race, etc.”
My question is “Why?” Nobody is implying anything negative about blacks. We are simply talking about a description of the person in question, so why is race such a taboo in only DESCRIBING a person?
