The game is hilarious, it's like someone who sits on /biz/, /fit/, and whatever the bleached general is made a game. I'm surprised someone being a "wagie" hasn't been brought up once. The dad and Mr. sparkles are my favorite characters by far.
For a big part, you can think of raceplay as either a humiliation kink or a praise kink, depending on the viewer.
Also, I think you are taking a game that's a shit post too seriously, you have a munchkin roided up black dude with a micro peen competing against a textbook chad who got rich in bitcoin, and you are asking about the realism of a white cock obsessed Latina? The game is literally meant to be silly and takes everything to the extreme.
