Gotta say, I've been out as a lesbian for 3 years and nonbinary for a year and a half. And I've noticed something.
Just because someone *always* gets your name and pronous correct, and angrily calls out anyone who forgets, doesn't necessarily mean they support you.
Conversely, just because someone struggles to remember your name and pronouns, or can't wrap their head around gender neutral/neo pronouns at all, doesn't necessarily mean they DON'T support you.
This is applicable to any situation really not just queer shit. Watch what people do, not just what they say, and you will find your friends. Someone might shower you with compliments and have common interests with you, but what happens when you tell them no? Do they get angry when they are corrected? Do they have kind things to say about other people?
My colleagues wouldn't know a gender-neutral pronoun if one hit them in the face with a dictionary, but they make sure I've had a lunch break and get home safely. They have my back if I have a difficult patient. They defend me against other staff members who like to create drama and bitch about people as if they're still in the school playground. If someone has something to say about me being a big ol' queer, they make it known that discrimination has no place in our unit.
My best friend in the whole entire world forgets my name and pronouns every day. When the organisers of her therapy group changed "men and women" to "people" and "he/she" to "they" in order to be more inclusive, there was outcry. Everything from the "it just doesn't sound right" grammar-policing nonsense to the "f*cking special snowflakes are offended by everything". She came down on them like a ton of bricks. She said if the organisers hadn't told them that it was changing, that they wouldn't have noticed. She told them they obviously haven't loved someone outside of the gender binary and they were missing out. She then told them how she had seen me grow and develop since I came out, and how in awe she was of the person I had become. No, she doesn't understand it at all, but why should that mean that she can't be there for me and appreciate how happy I am to be able to be me? Why should that mean, because you lot don't understand it, that someone with the same issues as the rest of the therapy group feels unsafe and unwelcome and doesn't get their issues resolved? As a result, a few of them changed their minds, INCLUDING HER OWN FATHER, and the rest at least shut the hell up about it.
A queer person who used my correct name and pronouns delighted in making me walk on eggshells, inventing reasons to be angry with me, convinced me I was a terrible person and even went as far as to try and turn me against my own therapist. They tried to tell me that my therapist only said I was a good person because she was paid to, and that because they themselves had a psychology degree that they could tell I had all these complexes and needed to work hard to be a good person, and it was unlikely I'd never get there. (I chose to listen to my therapist and stop being friends with this person).
A queer person who used my correct name and pronouns continued to do things that made me uncomfortable when I asked them to stop. Never said in as many words "you're not allowed to hang out with your friends" but conveniently had an emergency every time I had plans, and accused me of being uncaring if I needed my own space. They knew I had difficulty asking for help, but still got angry with me when I asked because I didn't ask "soon enough".
A queer person who used my correct name and pronouns told me they would look after me and they didnt. .
A queer person threatened to misgender me MORE when I corrected them.
I'm just saying, that if you choose to yeet everyone who doesn't get your name and pronouns right... that doesn't necessarily make you safe. We live in a very binary world. As much as we want that to change, it won't if we ignore or shout at the bits we don't like. (Believe me, I've tried).
