One time I heard a dude online compare new and obscure LGBT terminology to newspeak. This I think is one of the biggest examples I have seen of people with their whole chest ignoring the basic themes of 1984.
In 1984 the whole point of newspeak was that it shrinks. Ideas that could once be communicated now cannot. Everything is simplified as much as possible. You cannot explain complicated ideas of freedom or equality because the words no longer exist, or they don’t mean what they once did.
More specifically, there is canonically no word for “gay” in 1984. There are only two words for the entire spectrum of sexuality. “goodsex” and “sexcrime”. If you’re gay it’s the exact same as being a pedophile. And those are is the exact same as cheating on your wife, which is the exact same daring to fuck your wife just because you feel like it. Which is no different than literally any sex act that might offend big brother.
Do you see what’s happening? In 1984 can no longer ask your wife to peg you or something because the word for pegging is the exact same word for pedophile. And you can’t come out as gay because all you can say is that you did a criminal sex act, which means you cannot make a case for your rights either.
Inventing made up words to describe obscure things that previously lacked words would literally be a perfect remedy to newspeak. This language would counter every barrier to communicating the necessary concepts. Because it’s what literally every normal non-dystopian language does.
Keep this in mind especially in regards to what's happening in Florida right now. They associate LGBT+ content with grooming, define it as pedophilia or child abuse or sexual crimes or etc. Then they pass laws calling for sex offenders to be executed. Bigots or morons claim "Oh, why are you against these anti-child abuse laws?!" Because the state is trying to redefine LGBT+ activity and individuals as being the same as child abuse. For all the bluster and anger over "Grrr, words don't mean anything anymore! These terms I grew up with don't matter anymore!" the truth is THEY are the ones trying to limits what words mean because they want to associate certain groups of people with evil people to make more innocent/ignorant individuals be okay with hurting those groups of people.
In linguistics, we have a concept called The Sapir-Whorf Hypothesis. The basics of this concept are some degree of "If you don't have a word for it, you can't conceive of it."
Now, there are several degrees of this. The conception above is the strictest example of it, which is generally not accepted among linguists. A looser definition might be something like "It's much, much harder to talk about concepts you don't have words for." (For example, people who speak a language with more color words distinguish colors more quickly/easily than those who speak words with fewer color words).
Newspeak is weaponized Sapir-Whorf. To purposely restrict vocabulary to eliminate any thoughts of rebellion.
As pointed out above, progressives have been consistently adding vocabulary to the world, to better voice the thoughts and feelings of the oppressed and non-mainstream.
