The term "whitewashing", like many uses of the color "white" has nothing to do with race. Rather, it is a metaphor referencing a type of paint.
I may have simply misread the GP and picked the wrong meaning, but I was going with this definition https://www.merriam-webster.com/wordplay/whitewashing-words-...
Again, this is why I asked how it was the race-based version of whitewashing rather than immediately going into a debate. I wanted to clarify my understanding and see if I missed anything before jumping down someone's throat, would have been nice to get the same courtesy here.
I fail so see how providing you with the correct meaning is "jumping down your throat".
