DroneRights

The Borg referred to themselves as "we", and use the third person pronouns they/them. The Borg refer to Seven of Nine, Tertiary Adjuct of Unimatrix Zero One as "this drone", and use the third person pronouns it/its. Seven of Nine also did not particularly enjoy being referred to as "Seven". It was a concession made for the sake of efficiency and the comfort of the humans, but it voiced its dissatisfaction with the choice when it consented. As a nonbinary person, I have also consented to identifiers I didn't like for the sake of others' comfort. I recognise the experience and have direct empathy. Given that we are communicating in a text format, it requires negligible effort to refer to it as 7/9 and preserve the precision with which it wished to be referred.

Now as to 7/9's stated preference and opinion of Janeway:

JANEWAY: I've met Borg who were freed from the Collective. It wasn't easy for them to accept their individuality, but in time they did. You're no different. Granted, you were assimilated at a very young age, and your transition may be more difficult, but it will happen.
SEVEN: If it does happen, we will become fully human?
JANEWAY: Yes, I hope so.
SEVEN: We will be autonomous. Independent.
JANEWAY: That's what individuality is all about.
SEVEN: If at that time we choose to return to the Collective, will you permit it?
JANEWAY: I don't think you'll want to do that.
SEVEN: You would deny us the choice as you deny us now. You have imprisoned us in the name of humanity, yet you will not grant us your most cherished human right. To choose our own fate. You are hypocritical, manipulative. We do not want to be what you are. Return us to the Collective!
JANEWAY: You lost the capacity to make a rational choice the moment you were assimilated. They took that from you, and until I'm convinced you've gotten it back, I'm making the choice for you. You're staying here.
SEVEN: Then you are no different than the Borg.

It allowed itself to undergo conversion therapy to become a woman because it saw no other choice. It was locked in a prison until it agreed. That is not consent, that is coersion. It is survival.

How about Janeway misgendering 7/9?

Start with season 2 of TNG, proceed through TNG and DS9, then watch whatever looks interesting.

"Narcissistic behaviour" is an ableist dogwhistle. We don't talk about enabling deaf behaviour, or autistic behaviour, because those are disabilities we treat with a modicum more respect.

Infantilising mental disabilities is a dick move.

If you're not a psychiatrist, then you don't have the training needed to diagnose someone with a mental disability. I don't care whether your parents actually have NPD or not, but the risk of armchair diagnosing someone is that you'll just amplify stereotypes. You diagnose them because they meet a stereotype, and then you study their behaviour and reach the conclusion that narcisstists act like the stereotype, and then you spread your conclusion. It's citogenesis.

Also "narc" when used to say someone has NPD is straight up a slur.

No, I have NPD and we're called narcs sometimes. It's often used in the community as a shorthand, but generally if it comes from a neurotypical it's a slur. I'm aware of the other meaning of the word and I don't have a problem with it, but I tend not to use it because it just reminds me of the homonym which is actually offensive.

Can you add a content warning for carnism?

I've been in situations like that at work. I always ask what the senior worker's reason for doing things different is, because then I've benefitted from their experience too

Wow, you and I have very different tastes

There's a game about that. It's called Exapunks. You play as an anarchist hacker who is slowly dying to a degenerative disease that turns your flesh into electronics. The medicine to keep your disease from progressing costs 300 dollars a day, so you learn how to hack from a zine and then start making money for your medicine and taking down capitalism. At various points you have to use your hacking skills to reprogram your nerves so your body will continue to function. Send a virus to tell your heart to beat and so forth. The gameplay is based on a modified version of assembly and actual programming puzzles that make sense in the context of the cyberpunk world.
