I understand Brocolli is fine with it. (I didn't say he wasn't.) I just don't see changing Bond's sex or race. Bond is an established character. if you want, say, an Asian female secret agent, come up with a new character.
I think a gay black British man would do very well. The original Bond, both in the books and the older movies, despite the misogyny apparent of the time, also broke a lot of stereotypes for sex and licentiousness. Pushing those boundaries has been key to Bond for a long time. Why not a gay black man then, to hold to the same spirit.
Your comment changed Brocolli from a ‘she’ to a ‘he’ though… So maybe you don’t mind so much after all?
