"Why was a white actor cast as (character of color)?"
"Maybe it just happened that the actor who gave the best audition was white!"
"Uh huh, and how many actors of color were allowed to audition?"
"None! The casting call asked specifically for white actors!"
"…THEN OF COURSE THE ACTOR WHO GAVE THE BEST AUDITION IS GOING TO BE WHITE!!”
"Oh, so you’re saying they deserve the part!!"
This is why the “best audition” excuse for whitewashing is bullshit
