Look, you know this is not some gotcha to smuggle in evil orcs or some BS like that. But as you note, it gets weird when we apply biological essentialism, a concept that is mainly used about humans, to actually different species. And it is technically biological essentialism to say that birds have wings, just like it is to say that humans are smarter than chimps.
That isn’t what biological essentialism means. But, I don’t want to get bogged down in semantics, so whatever term you want to use for “belief that ‘human nature’, an individual's personality, or some specific quality (such as intelligence, creativity, homosexuality, masculinity, femininity, or a male propensity to aggression) is an innate and natural ‘essence’, rather than a product of circumstances, upbringing, and culture,” just imagine I used that term instead whenever you see me use “biological essentialism.”
It just happens to be that some of these things have been said about real groups of people while some (probably) have not. And yeah, it is pretty easy to spot things that are unlikely to come across as problematic, such as wings or breathweapon or some purely cosmetic things.
Did you just call wings and breathing fire purely cosmetic? If you believe that, we are operating on very different understandings of what cosmetic means.
(Though closer we get to things that things actual people have or are describes as that too gets problematic. Drow skin colour is just cosmetic, but it definitely is not insignificant issue!)
But it is far from clear cut.
And there’s value in discussing the areas where it is unclear! Let’s do that instead of whataboiting over things that are obviously not problematic.
You mentioned changeling shapeshifting. Not necessarily so innocuous as 'others' that look like us infiltrating our society definitely is a racist trope.
And if changelings were depicted as an inherently duplicitous race who used their shape shifting ability to infiltrate societies of other races for nefarious purposes, this might be a valid concern. That would be essentialism. Simply having the ability to shapeshift is not a problem, unless it’s used to define
essential qualities of the race.
And then there of course are things that just measure capability in other way. Due how D&D mechanics work speed is not dependent on ability scores, but that doesn't make being fast conceptually different to being strong. And of if being depicted strong is problematic biological essentialism, then it doesn't matter whether it is done via strength score, powerful build or even just in the lore.
A race being strong isn’t biological essentialism. They’re larger, they have more muscle mass, that’s just a physical attribute. What’s problematic is when those physical attributes are used to define essential qualities of the race. When Goliaths are not just
strong but
a race of natural athletes. Unfortunately, with the way abilities interact with class in D&D, this essentializing is unavoidable with racial ASIs.
D&D mechanics are not social justice issue, what they depict might be. Even pretty trivial seeming things may seem problematic to some. A while ago there was discussion (here? somewhere...) about whether Goliaths were 'black-coded' due their overt physicality.
Yes, there will always be someone who can find something to take issue with anything. Our goal should be to achieve a reasonable standard, not to make the game 100% critique-proof.
I was creating my current setting a while ago when the great orc flame wars raged here, and I thought about this quite a bit. And whilst I fully agree that we should endeavour to remove clearly problematic elements and I have been complaining about D&D's racist depictions of certain things (orcs and drow mainly) at least since the 3rd edition. However, I also came to the conclusion that if the standard is "would this be racist if it was said about human ethnic group" then we pretty much cannot (and shouldn't) have non-humans.
That seems like a silly conclusion to come to, perhaps based on trying to come up with a deterministic rule instead of evaluating on a case-by-case basis
Anything that would be left would be some cosmetics and perhaps some superpowers*.
And what would be wrong with that? Cosmetics and superpowers are cool.
Eberron is usually considered to be very good with these things, so lets look at its orcs "The orcs of Eberron weren't formed by Gruumsh, and they aren't inherently driven to evil. However, they are an extremely passionate and primal race, given to powerful emotions and deep faith." If I was to describe a real life human ethnic group thusly (ignoring the Gruumsh part obviously) it would be incredibly racist. Ultimately the issue is, that in order to describe non-humans, we have to describe how they're different from humans or at least stereotype then into some sort of extreme form humans. But describing any real human group that way would be racist. Even things like "industruous, holds grudges and loves gold" would be problematic.
Yeah, I don’t love that description of orcs either. What it, and your “industrious, holds grudges, and loves gold” example have in common is that they describe essential qualities of the race. Those are all perfectly fine traits for individual members, or even entire groups of those races to have. They just can’t be inherent qualities of birth. Make it nurture instead of nature.
* And for a game that needs to be balanced, even superpowers might be an issue, as having them necessitates that the group is worse at something than humans.
I think this concern is overblown.
