That comes across as painting the African-American experience with a pretty broad brush. This Bruce Wayne is still wealthy, privileged and somewhat insulated from "the real world". I think seeing one's parents gunned down would be a traumatic life changing experience for a child no matter what their race or economic status.
The point wasn't that it wouldn't be traumatic for a rich black kid (of course it would) the point is that it would have an entirely different meaning and connotation to a black kid; even a rich, relatively privileged one.
As has been suggested over the last few months, I've made a point to take extra time to listen to and process what African Americans have to say on this subject. One of the common threads I noted was that the sense of
"we're not ever truly safe in any situation". Regardless of whether they're rich or poor, vulnerable or privileged, it seems like that threat is a constant day-to-day psychological pressure that is always at least in their peripheral awareness. Shoring of growing up in a literal war-zone, that's not something that any western white person can ever truly comprehend because it's something you either live, or you don't and most of us just don't.
So when you apply this to Bruce Wayne; you change the entire social context of his trauma and the source of his righteous cause. For a black Bruce Wayne it wouldn't be some total unjust bolt from the blue, it'd be just a continuation of a pattern of injustice. These things matter when creating a character.
Maybe in 100 or 200 years it won't matter so much, but in the here and now I don't think Batman is the right character to appropriate the embodiment of Black Pain. That's more Luke Cage's beat.
It only becomes "Crime Alley" after the Waynes' murder.
That point seems to vary from depiction to depiction. Regardless; rich people walking through a dark alley at night is never a smart move in any city.
I obviously disagree with the idea that Bruce Wayne can't be black since I inadvertently started the whole convo

but there has been some recent push back against the idea of making such characters POC for essentially the same reason
@Reverend has used. There was a big article the other day floating around progressive circles that the real reason James Bond has to stay white is because he's the ultimate symbol of English Imperialism and making him a POC "white washes" (heh) the entire imperialist nature of the British Empire, making POC seem like willing participants and not victims.
Again, I don't necessarily agree with the position, but it is an interesting and fair take.
Despite being British, I honestly don't have a lot of skin in the game (no pun intended) when it comes to Bond. Never been much of a fan and only have a passing familiarity with a handful of the movies over the years.
That said, I feel like the character is so inherently broad and open to interpretation in a modern context that I don't see the character as being intrinsically white, or indeed male.
Unlike Batman, Bond is more of a cipher and the storytellers can imbue them with whatever traits the story demands. Now if they were to go back and make an old school period Bond movie set in the actual time the books were set and/or written, then yes I think he would have to be white, male, misogynistic and a product of the old boy network. Anything else would feel disingenuous, inauthentic and a little like trying to rewrite history.
In a modern context; I have zero problem with Idris Elba, Thandie Newton or Dev Patel taking on the role of 007.
Not sure I buy the Imperialist take so much though. For one thing it's originally a cold war based story and the Empire didn't survive long post WWII, and one would assume the focus would have been on the Soviets. Now, enabling American Imperialism in the same period through supporting their proxy wars is a whole other thing and possibly a tad closer to the mark...
