Well that is why I asked. I have heard whitewashing used quite a few times in this way, though usually in the context of film or TV. I very well could have just missed it in the moment.

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.
