I can tell you that Ian Fleming would be very angry at a Black man playing Bond.
He was about what everyone else was in his day but that would be considered racist today. In the book “Dr. No”, he described Dr. No’s henchmen as “Chigroes”. He said they had the intelligence of the Chinese and the brutality of the Negroe. He did have one positive Black in the book, Quaryls.
I think that, for me, it boils down to the detestation of the common practice today of saying something is another thing, while either knowing full well it isn’t, or not caring to know.
