Look, I'm going to be as frank about this as possible because this has been going on for half a decade and it's very tiresome
"Blackwashing" does not bring people together or shine light on anything. It's the same mentality as all the afrocentrist retards that are like "original Hebrews were black" or "it was Africans who taught Europeans how to bathe and do plumbing" or "actually the vikings were black" and so on. It is insecurity made manifest. It is done by those who only ever acknowledge themselves, associate themselves, and identify themselves by their skin color and realize that skin color alone does not give one pride or culture, thus will hijack and aggressively assimilate works of others to feel better about themselves.
"Whitewashing", or at least whitewashing in this particular instance, is a combative meme used to make fun of the insecure individuals that promote or create blackwashing. Because at the end of the day, the ones who unironically promote/create blackwashing do it to "fix art" or are also in the business of harassing artists that use a "wrong" shade of color for a character. Whitewash trolls when then go "well fuck you and your sensibilities, I'll do everything in my power to offend you for a laugh"
I know I'm wasting this time and effort on a Terminally Online Free Palestine Slacktavist (TOFPS), but fuck it I am really tired of this dumbass "discussion". If you legit like blackwashing, please just embrace other cultures and come to terms with your own insecurities. Grow as a person and you will enjoy life and yourself a lot more. You are more than your skin color.
whitewashing = made primarily for ragebait and removing representation of minorities, usually made out of anger or spite
blackwashing = made primarily to bring people together and shine the light on those not normally seen, usually made out of pride and want for diversity
