1- People had no problem with Najica Hiiragi...:
...a woman as a secret agent
2- Nor a black* man voicing a character played - in the first three of a set of a certain saga of nine films - by the late great Dave Prowse**
4- So you tell me.
*- Finn. Before then - and in the last trilogy part of said nine films - Lando Calrissian. Problem?
**- A white man from Southern England with a West Country accent. So why no complaints about a role not played by an American...?!
C-3P0. Wicket. Finn. Rey.
And as Daniel Craig's Bond's CIA counterpart Felix Leiter was played by a black man, there's your entire 'argument' crashing & burning just as hard as Blofeld's helicopter onto Westminster Bridge at the end of "SPECTRE".
Who plays Guardian of Bifrost Heimdall in the Marvel Cinematic Universe. Who is now Captain America.
Shall I continue, or have I sufficiently obliterated what's left of said 'argument' of yours, CourtingDisaster...?!
