Let's frame this as a logical equation.
If race = nonexistent and purely fictional, then the derivatives of that race don't exist either — regardless of whether they have real-world parallels. The mind cannot imagine something out of absolute nothingness, so any fantasy race is just a mishmash of real-world traits, an artistic concept, not some sacred tablet embodying the real and immutable nature of a group of people.
Consequently, representation in fantasy is fundamentally impossible. It's literally an ideological myth. You can't create it intentionally no matter how hard you try, because even if the author explicitly says, "these are africans," they are still going to add magic, an alternate world, their own biases, different cultural layers, and a fictional history. The subject immediately stops being a real black or even an objective, true depiction of one. It is no longer representation; it is a complete abstraction, a fictional construct that has nothing to do with the real world. To claim that representation can even exist in a space built entirely on myth and invention is a fundamental delusion.
And since there is no representation, talking about "erasing representation" is completely moot. The player is just tweaking fiction to their own taste — and they have every right to do so, just like any being with free will. As for why they do it? That's their own **** business. Nobody owes a pack of reddit losers any explanation.
