That article was really... ugh. No, Batman doesn't have to be white. No, Superman doesn't have to be white. No, Diana doesn't have to be white. "Diana is Mediterranean, which counts as Caucasian for these purposes." YUCK. Fucking YUCK. I'd say if those characters and Aquaman have any primary characteristic that can't be overriden, it would be their genders. Admittedly, Superman might be trickier to racebend given he lands in whitebread whitey-Kansas, but I could easily picture Batman Latino and Aquaman Asian. One's in a major metropolitan city and the other's in the fuckin' ocean. They could be anything. And Diana could easily have darker coloring than what she gets typically fancasted as. Not everyone in Greece is lily-white. She could be black. Africa is right fucking below Greece for crying out loud. I find it interesting how much they wanted to tool around with Flash and Cyborg when those are actually the ones I'd do nothing to myself. That they didn't want to touch the main trinity in particular is EXACTLY why nothing's diverse enough to begin with.
