Umbran: How the heck do you get from describing how technical writing -- and by YOUR OWN extension, game writing -- should look: ... to this weaksauce "no right answer" cruft?
Oh, I admit it wasn't a very well constructed step. I'll try to get to the same point in just a moment or two...
Even if we were talking about all things, though, singular "they" would still have no utility.
I don't think that is correct. I will accept that it provides no new utility - you can always reconstruct a sentence so that some word(s) other than "they" is (or are) used. Singular "they" is certainly redundant with several other ways of saying the same thing.
That's not a strong argument against it, though. Redundancy is the root of flexibility, and is what allows language to flex to meet the needs of different styles. Redundancy is what enables us to write poetry. In heavy excess, it might be a problem, but I don't see that the language is having difficulty due to the excessive number of ways we can construct a reference to a singular gender neutral object.
There's no such thing as "linguistic Darwinism" within a single language.
So long as there's more than one way to say a thing, there is competition. If one form of saying something is truly dreadful, it gets dropped in favor of some other way of saying the same thing.
You're confusing "provides a benefit" with "hasn't killed the species yet".
No, I am not. In even a simple evolutionary model, a thing may be beneficial, neutral, or harmful. Outright bad and harmful things get weeded out. beneficial things tend to get amplified, and neutral things tend to just sort of hang around until they become either harmful or beneficial.
I'm saying that this particular construction has been at least neutral, and possibly beneficial. If it were really awful, a few centuries is enough time for it to have fallen by the wayside with so many other archaic forms. I'm saying the verdict of centuries and millions of people using the language so far trumps you.
Seriously, your argument implies the human appendix is useful. Your argument is flawed.
If you aren't speaking mathematics, then every argument, every analogy, has flaws.
Unless you have some evidence that singular "they" is on the way out (like the human appendix), then I don't see your point as very strong.
Singular "they": it never helps.
Your argument is flawed.
You present a couple of example constructions, and then assert that since use of the word is painfully ambiguous in those examples, that the use is bad in any and all contexts. But, since you are choosing the examples, they are cherry-picked to support your point. Furthermore, you present no evidence other than your personal assertion that the generalization from your examples is valid for the rest of the language.
Your position so far ultimately relies on your personal authority to assert that generalization.
