We’re talking about the definition of words and how censorship is a tool of authoritarianism.
No one can describe a single moment a society becomes authoritarian, and asking such a question is obviously specious. The devolution happens incrementally over long periods of time.
I’ll interpret this circular answer as “no impact whatsoever upon me personally, or upon society in a way that I can concretely identify.”
This argument seems to otherwise come down to “people are adding nuance to a word that I believe to be very clear and simple, this change makes me uncomfortable, and I’m going to die on this hill to keep things the way they used to be!”
I’d also like to remind you that neither disagreement nor social pressure is censorship—even if you ultimately succumb to that social pressure or feel a chilling effect. (Are you “censored” if people throw tomatoes at you after you call a Black person the n-word?) Censorship is when the government threatens your life, liberty, or property if you express yourself in a certain way.
