How is that true in a way different from other industries? I do think there's no necessity for the race of the VA to correspond with the race of the character. That might be because I don't have a good grasp on the arguments otherwise though.
The argument I've heard in favor of VAs matching their characters is to avoid laundering white perspectives to minority characters, which would make sense if the VA didn't have their livelihood on the line when asked to read from a script written by a cishet white man. I feel like requiring a minority do that makes no difference other than providing a cover of legitimacy for the words said.
But as a cishet white male myself, maybe I'm mischaracterizing the argument, I'd be curious. I have asked my (racial minority) wife at one point a couple years back and she wasn't sure.
It's a given that there are insensitivities in hirings, but I struggle to imagine a way in which that would be unique to voice acting specifically.
That's a hill you will die on from old age. I have never once heard someone say pineapple is not a valid topping in a way I thought was meant to be taken literally and not as an exaggerated way of saying "I don't like it".
