Hmmm, I honestly thought this was going to explore the topic of people that are in the closet about their gender identity. Or maybe, plural people. I find this video more confusing than anything.
I think the way you describe it is perhaps too abstract for me to understand the points you're making.
I find this passage rather distressing however "Pronouns reference the framework you expect someone to use to process your words". I find that language scary sounding. It feels like specifying someone's pronouns is forcing an ideology or status on someone and I just don't think that's true at all.
I also don't think saying gender has "dedicated pronouns" is really accurate. Neopronouns exist and they still confer meaning to the person so I don't think it's a defined set. Different languages also have different pronoun systems which complicate creating a specific set.
I find the third argument kind of odd. I think that displaying pronouns in general has the same effect you're describing without the need for different pronouns in different spaces. The same thing is true for things like a role bot or other tools to allow people to display their pronouns.
Well, you can disable window controls in gnome and KDE afaik if you want. Then you'll only have the various app-specific buttons that are necessary for functionality.
If you're looking for every app to have a vim-like interface or something, well, that seems a bit unrelated to CSDs.
