So on other words, "newspeak" when said by a conservative (rather than someone who actually read the book and understands the concept) is a dog whistle used to complain that English is a living language, and usage of words change...
As usual, the explanation you come up with for an opponent disagreeing with you is make-believe -- a pure invention ungrounded in any observation. You are not competent to model other people's minds; you know this about yourself; you ought to take this into account when you feel the urge to impute disreputable thoughts to people.
Of course English is a living language. Of course usage of words changes. You have seen exactly zero examples of anyone complaining about that here. But English is
a consensus of the usages of all its speakers. The language changes when the consensus changes. Demanding that people change their usage is not sufficient to change the language and is not evidence that the language has changed. Adoption of a new usage by a narrow subculture is not sufficient to change the language and is not evidence that the language has changed. Pointing out that you personally are not the Academie Anglaise, and that you personally have neither the power nor the authority to change English by mere force of your wishful thinking, and that you personally have not supplied any evidence that the consensus of English speakers has in fact changed to whatever you wish it were, do not constitute complaining "that English is a living language, and usage of words change." Your entire line of argument is asinine.
How dare we understand the foundations of common words at an academic level!
You misspelled "make up a just-so-story to rationalize creating new technical jargon, and then pretend new jargon makes the old usage wrong."
Plenty of argument has been made to demonstrate than "man" and "woman" are social concepts only loosely linked to physical realities,
Certainly. And then you promptly discard that conclusion that was plentifully demonstrated, and indulge yourself in the fairy tale that "social concept" has nothing to do with society and instead means "it's whatever my ideology proclaims -- society's concept be damned".
A person's gender is not the category he puts himself in; it's the category society's consensus puts him in. That's what it is to be a "social concept". A person is of course free to categorize himself any way he pleases, but he cannot force others to categorize him as he pleases. Categorization is the fundamental linguistic operation, prior to all considerations of naming and syntax, and
all speakers of a language are free to do it any way they like. It's called "freethought" -- deal with it. And if it turns out most of us freely choose to do it
the way we observe others doing it, so that we can more easily
communicate with them, well, that's where
consensuses come from. That's the reason it's possible for languages to work in the first place. This is not rocket science.
The ability to think and express this concept -- the concept that a person's "gender" is socially rather than individually chosen -- is what you have been attempting to suppress by promoting your Humpty Dumpty language: your idiolect in which you use "gender" to mean "gender identity" and in which you retain no word still meaning "gender".
