You might want to go back and review that quote about the continent of Africa again. It’s an analogy. Think about how you are viewing the continent of “white men” - if you look closer you may discover that it’s actually made up of many very different countries (people).
Frankly, the whole idea that calling your cable or phone company and asking for a discount is a race-based activity is beyond tripe. I don’t even have a word to describe what a ludicrous concept that is.
