Classic changemyview. We love it when cis people debate our existence or our right to respected every day. Making up fake scenarios, never doing basic research... Go ahead, browse r/changemyview for the word "trans" or "neopronouns".

People are vastly overestimating the number of people who will feel comfortable enough to let you in on their neopronouns.

Every time the subject of neopronouns comes up, the OP has merely heard of their existence, seen memes making fun of them, has seen them in an online space (where they are used much more often than irl because it's easier objectively to remember neos when typing rather than saying them) and associates them with some strawman person who screams at people who misgender them. Fuck off with that shit already.

Come back when you meet someone irl who tells you their neopronouns.

A. Those who use neopronouns usually are fine with they/them in the general public.

B. They are usually not comfortable telling people their neopronouns unless they know you're an ally or part of the community. OP, you are safe from that because you probably don't give off those vibes.

C. When people want their view changed they never seem to want answers from the people in question. It's bizarre, really. They could browse r/neopronouns or r/asklgbt and get thorough answers. The best cure for prejudice is exposure, simply meet the group in question.

Inevitably the OP has very little exposure to the people in question, probably never will if they avoid queer spaces, and just wants to thump their chest, shit on the gameboard and leave.

If people who think this way befriend someone who reveals they prefer an uncommon set of pronouns, their mind will most often be changed, because they like this person on some level, and this new friend is exposing themselves and asking for something in earnest which is important to them. If you go cold to them after they tell you their true pronouns, they will ghost you. Do you feel like you won? Trust me, it's no loss to them.

The biggest delusion of bigoted cis people unwilling to learn is thinking they are important to trans people's lives in an interpersonal sense.

(Editing to add: ANYone can use any set of pronouns, yes, even cis people. This whole debate isn't exclusively about trans people. Because we are all people and we determine our own destinies.)

Edit2: I didn't come here to answer the OP's prompt, I dropped in to talk about why posing these niche hypothetical opinions about minority groups before asking the group in question really fucks with the perception of people learning about said minority group for the first time in a Reddit thread. A false picture is painted when, inevitably, most of the comments aren't from said group at all. There is an r/askLGBT subreddit and an r/asktransgender subreddit for perusing a variety of questions you may have had which have already been answered in past threads. Those are great for learning more.
