I expect the entire thing will be ignored. Would be quite surprised if it happened in any capacity. But you never know. Dude's a villain, he's not supposed to have good morals or ethics, so exploring racism through him opens up doors you can't go through with somebody like Sam Wilson. Still, I wouldn't think they'll go that route; too sticky a topic.
And yeah, some folks define racism as a white-only thing. Which....is not something I agree with. At all.
