"They" is plural. Why are people saying it? Are people to lazy to make a new word? It is stupid, plain and simple. Seriously, how hard is it to make a new word? Is there a new word? My sister's (or brother now) is asking me to call... "it" a "they". Why? Just ask me to call him/her/what the fuck a "he"? "They" is an already established word, don't fucking complicate it! Five years ago edgelord preteens called people "it" as an insult, and now it identifies gender? Wait, is it gender? Is it sexuality? Is it some other bullshit someone pulled out as a way to identify themselves to jump on the bandwagon? Is it legitimate? Is it a joke? Am I the only person confused and fucking sick of this stuff? AM I?
@HylianBran "it" typically is used to refer to objects rather than people within English, that's why "They" which is actually not plural, but one word that is both singular and plural at the same time like deer but it is different since iirc it is a preposition. Even then people just want to be referred to what they feel comfortable, and sometimes you just gotta read the room to understand that being a bit open makes life easier
They/them has long changed to also be gender-neutral singular pronouns and most people already use they/them when referring to someone they don't know the gender of. I actually use they/them pronouns because I am non-binary, but I am also ok with she/her because they aren't male pronouns and that's what matters more.
@HylianBran consider this - and a pre-emptive "I don't mean to be reductive in any way and I hope that it doesn't come across like that" - imagine you're talking about a business, let's say Google. Google is not really a genderable entity, not a he or she, and you wouldn't refer to them as that - exactly how I did there. Google is a very large company, and recently they've announce a new feature being added to a few of their projects. Just like that.
Now, not to say that a person who wishes to be referred to with non-gendered pronouns should be considered a business or anything like that, of course. But in the same vein, if for whatever reasons, someone doesn't want to or isn't comfortable being referred to as he or she, doesn't identify with a typical gender binary, then if you're talking about a person and aren't going to call them "Joe Shmoe", their name, then the next appropriate pronouns to use are to refer to them as... well, them. That's what they're comfortable with, and that's about all there is to it.
The explanation, when needed, is much more complicated and verbose (IMO) than the implications of it. At the end of the day, everyone's allowed what they're comfortable with. Obviously you are going to make mistakes sometimes, sometimes you see a guy that looks like a girl or vise versa and you may make a mistake and refer to them with the wrong pronouns. Honest mistakes happen, but when (the royal) you know what their preferred pronouns are, and instead repeatedly use the wrong pronouns on purpose - well, that just makes (the royal) you an asshole.
Spoken from the perspective of a cis guy who's always used the same pronouns, so I apologize if I'm off base in any way.
@Sicklyboy So I'd be an asshole if I, in a theoretical timeline that is surely never going to cross with ours, said the incorrect pronoun that wasn't very well defined to begin with? In all seriousness, why aren't these well established by this point? Actually, I take that back. Everyone else seems to already be informed on this, so why aren't I? I apologise for wasting all of your time (speaking to "the everyone"), but I am very, VERY frustrated by this. My sister lives in a "coo-coo for coco puffs Facility" and she seems to get it, so why can't I? I am destined to be an eternal asshole? Huuuhhhhh???
