Just because we lived in times where only white people were getting the best jobs doesn't mean we should be heading in the opposite direction now and prevent them from getting work because of their skin color. Everyone should be getting a fair shot based on their qualifications and talent.
Lots of talk in voice acting about how white people can't voice black characters, so despite them perhaps being exactly what the director and writer had in mind for the character, they now have to give up the role to make room for Black VA's. The most obvious recent one being Cleveland Browns VA making a big virtue signaling show of happily stepping away from the role.
But what about Phil LaMarr? Voice of Samurai Jack, a Japanese character? Shouldn't he be forced to stop voicing the character to make room for a Japanese VA? Of course not, anyone should be able to voice any character regardless of the actors race, or the characters race. Phil LaMarr is an amazing voice actor, and I love hearing more of him. It'd be a damn shame to take him off of any role. So why is it only made a big deal, one way? but not the other?
I remember reading some voice actors complain about this, after all now you won't be able to voice some really cool characters as a black man, your role will usually just be reduced to token black character, since now if this were to be taken across the industry you would no longer get to play Samurai Jack, or whoever. It's absolutely ridiculous, can only Asian Americans dub Anime now?
Any person should be able to voice any character. In the world of voice acting, voice is the only thing that should matter. Voice acting roles should be done, and in some case's have in fact have been done blind.
I think the line isn't clear outside of the world of acting though, it isn't just a voice, looks matter too. In the '94 Flintstones movie Rosie O'Donnell got the role of Betty because of how well she captured the voice of Betty, but everyone and there grandma complained about how terrible she was as Betty in every other way. It's often listed as one of Hollywood's worst casting choices of all time. Visuals do matter on characters that have a distinct, predefined representation. Rosie O'Donnell would do amazing as a voice actor for Bettie, but not as an actor for Bettie. So it is not a simple as voice acting where only voice matters. So much more matters in the world of acting.
The argument that many of these roles are handed out because of qualifications or talents has no real backing, although my argument admittedly has no more backing then yours. It feels like Hollywood is just pushing some sort of propaganda. Like a modern day, hidden take on Blaxploitation, take a white character, make them black and then sell it to African Americans and SJW's as brave and progressive. More often then not it doesn't feel authentic or organic, just a form of easy advertising and virtue signaling. SJWxploitation?
Especially since so very often you see it with white characters turning black. Don't recall any of them turning Asian, or Mexican. Only one I can really think of that goes the opposite way in recent memories is Scarlett Johansson playing Major Kusanagi in GitS, and everyone screeched about that as whitewashing. It was a big deal for a lot of people to cry how that role should've went to a Asian actor.
So why is it that only one of these things is okay? If you cry about a white character being black you are racist? But you cry about a Asian character turning White you are not racist? I think it is a complex issue that deserves a lot more thought, discussion and argument then anyone is willing to give it.
