Also here's my take on race-bending, race-lifting, whatever you want to call it: The characters from the era of comics that Gordon first appeared in weren't white because it was integral to their character, they were white because you could either be a hideously stereotypical caricature... or you could be white. That's why I haven't cared that a modern take on Archie would make Veronica Latina or Reggie Asian, that's why I haven't cared that Momoa is Aquaman and that's why I don't care now that Gordon will be black and Catwoman will be a woman of color.
Now, I don't care to see Fandom try to dictate this stuff (that James Bond HAS to be black or a woman, or else he's irrelevant, for instance), but if it's what the filmmaker wants, let them be.
You like your Commissioner Gordon to be white? Okay. You've had that, and truth be told, you'll probably have it again. But in the meantime, Wright is a helluva choice. Take it as a win and carry on.
