Isn't Julia a member of some sort of anti-sex league, meaning there's a lot of bad faith involved in their relationship from the get go?
Also with respect to the attitudes on women and proles, although I don't think it's entirely written in the character's point of view it feels like there's a lot of unreliable narration going on, or at least you get a lot of stuff from the perspective of a person who grew up in one of the most absurdly totalitarian regimes in literature. Which is to say, it didn't feel prescriptive most of the time to me.
See also: "proles", as in the contempt is baked in to the language, which we know the regime is actively trying to hold in a tight leash.
That must have been really subtle, all I remember is a concern specifically about how a sufficiently totalitarian regime may try to weaponize language as a further means of subjugation, not that language evolving is bad in principle.
