What hurtful prejudice, exactly, if I may ask?
I'm also disabled, so don't wave that flag at me - let's just talk sensibly, and ideally in good spirits (If I come across as forceful with any of the following, I promise it's not my intent to be aggressive or to offend).
No-one is getting 'written out' here. People with disabilities aren't represented in this game, I'll agree with that - but that issue is not in any way the purview of this thread, and has nothing to do with it.
What erasure are you perceiving is being asked for here? It sounds like you're asking for an entire race of creatures to be designed and depicted in a way that makes them appear to have a major disorder in order to 'represent' people with similar disabilities - No, that's not helpful. It's destructive and harmful, because it reinforces othering and segregation. I'm all for people being able to elect for various disabilities to exist for their characters, and if the game could handle character design to that level and do it effectively it would be great. It would also create angry waves of people who weren't satisfied that it was done well enough for their liking, or who found it offensive for different reasons, but that's a different problem. Making an entire character race present a clinical disorder for the sake of representation is never going to be an acceptable course of action - or how would you like to be treated as though you were a completely different species of creature, because of your disability? Do you not find the entire concept of picking "the disabled representing race" to be, itself, an incredibly gross concept? People suffer that exact experience every day, and it's not a good thing (It's horrible, in fact. There are plenty of humans out there who will treat you like you're both infantile levels of stupid, and also act like you can't hear them, just because, for example, you talk with your hands rather than your mouth, as I do) - there is zero reason to entrench that in a video game.
Real humans (H.Sapiens that is) have large skulls for a reason; to hold our large brains. I looked up H. floresiensis and it's fucking fasinating, and how it's different to micrcephaly and pygmyism. I'd recommend reading up on that first. But, to not diverge too much, the models shown would need a lot more in the the forehead region to carry the sentient, sapient processing capacity of a person.
This is not quite accurate. If they were simply smaller humans, as in, actual humans, with human physiology, but small, then yes, they would definitely struggle. The point is, however, that they are
Not humans. They are a independent creature race - an entirely different species of being. They aren't going to have the same cranial physiology as humans, if you want to go into it that far, precisely because they are much smaller mammals that present human-level intelligence. If you looked at halfling brain, for example, you'd find that it was exponentially more crenulated than a human brain (that is, they'd have a far, far greater density of gyri and sulci). They don't need to have bulbous or deformed heads because they are not human, and they are able to have an independent neurobiology that suites the creatures they are designed to be, with healthy-looking proportion (and yes, I will continue to use that phrasing; no offence is intended, but a disability is a disability, and a disorder is a disorder, and they are not healthy, by their very definition. This isn't a judgement on anyone who lives with such things, it's just a factual statement). (If you'd like some more interesting reading, you could look into ravens - who possess human-level intelligence and a capacity for abstract thought, planing and reasoning, emotive attachment and grudge-holding that surpasses all other primate species and even pre-adolescent humans; they don't have large lobes anywhere, they just have independent and different neurobiology that suites their form, not ours)
Right now, the halfling models don't look like halflings. They look far more like humans with a particular form of dwarfism. They shouldn't. They're halflings, not humans with a particular form of dwarfism. I'll never stand in the way of more player freedom with character design and choice, nor of the ability to feel represented, seen and acknowledge, in video games or in anything else, but that is not in any way an issue relevant to this thread. Trying to say that the entire halfling race should be "Used" to serve as the representation point for certain groups of people with disorders or conditions is not progressive; it's hurtful, harmful, disrespectful and offensive - to halflings
and to people who bear those disabilities or conditions.
Representation is good - the ability of everyone, no matter their status, to feel like they can find something or someone in the game to identify with or to feel seen and acknowledge by the presence of, is a good thing... But stepping on other beings and erasing their uniqueness in order to champion that idea is committing the very crime you're speaking out against. It's not a relevant part of this thread, but I'd definitely encourage you to make your own seeking more and better representation in the game in general and regardless of your race of choice, if you wish to. I'd even support it, most likely.
