Shot down for utter stupidity? Doubtful. Elba has been discussed as a possible next Bond for years. Not because he’s black, but because his skills/style/etc as an actor would be a good fit for the role.
I suspect it is because he is Black.
I doubt he has any acting skills which are particularly suited to playing a Scottish spy.

No black actor is a good fit to play James Bond anymore than than a white actor is a good fit to play Mammie on GWTW, who was also a fictional character.
