This assumes that censorship is inherently bad. Censorship against speech regarding the government should be protected. However it's perfectly legitimate to censor harmful ideas, and many countries censor hate speech. We censor people's ability to physically and emotionally harm others. We censor threats. Censorship isn't inherently bad, and is already used functionally everywhere, just ask ChatGPT.

I do however think censorship can be dangerous. I think the censorship we see in public forums (including lemmy) already treads on the toes of legitimate intellectual conversation of objective views on hate speech and offensive language. Tone policing is incredibly intellectually disingenuous, but is widespread because feelings trump literacy. I think the censorship of individual words is supremely dangerous because it also bans or limits the conversation around those words, their usage, etymology, and understanding their use. Comprehension of offensive things is just as valuable as understanding anything else, if not more so should you wish to fight them, but censorship of offensive things without context destroys the capacity for understanding to permeate the social consciousness.
