Melissa Harris Perry has a lot of feelings about Star Wars, primarily that it's racist, because Darth Vader was voiced by a black guy but played by a white guy.
The part where he was totally a black guy whose name was basically James Earl Jones...but while he was black he was terrible and bad and awful and used to cut off white men's hands, and didn't, you know, actually claim his son, but as soon as he claims his son and goes over to the good he takes off his mask and he's white.
Maybe she doesn't acknowledge the prequels as being real, and who can blame her for that, but Anakin/Vader is a white guy in those and he kills so many younglings. He also first "claims his son" while he's still "a black guy" (a whole movie before he takes off his mask) and, well, if you've ever heard Darth Vader's on-set voice, you'd understand why they dubbed over it with James Earl Jones:
If there's one thing the denizens of Twitter, the Internet, the world really, are good for; it's banding together and taking up arms to stage a rage-fueled protest against anything remotely or absolutely evident of the proverbial 'whitewashing'. George Takei led the charge somewhat recently on that whole Doctor Strange business. Netflix went and kicked the hornet's nest with their new trailer for Death Note.
