Never watched the Bojack Horsemen series. I looked this series up and expected to hear Angela Johnson's nail salon lady, but it was just Brie doing her normal voice, which sounded like most second-generation or later Asian American women I know. It seems what Brie thinks was regrettable was that she wasn't the same ethnicity as the character: "I now understand that people of color should always voice people of color."
Granted, Brie is entitled to her opinion, but there seems to be a growing sentiment that white people portraying brown roles is unacceptable, and yet it's increasingly acceptable for a growing number of brown actors to take on traditional white roles (e.g., Heimdall in Avengers), including historic figures that were white (see for example, various characters in Hamilton and Mary Queen of Scots). I'm not in favor of anyone putting on makeup to make them look like another ethnicity, especially when the end result is a gross caricature, but there doesn't seem a great deal of difference in adapting the race of a character. If we're gonna call one instance an artistic adaptation, then that standard should be applied across the board, otherwise it should be spurned across the board.
