Social media posts inciting hate and division have “real world consequences” and there is a responsibility to regulate content, the UN High Commissioner for Human Rights, insisted on Friday, following Meta’s decision to end its fact-checking programme in the United States.
Another perspective on the Lemmy situation is that, for example, I can sincerely say I believe free speech has merits while creating a book club where political discussion isn’t allowed. Some would call that censorship, but restricting a certain community doesn’t mean I approve of unconditional societal censorship. “Censorship”, like many abstract concepts in the liberalist worldview, doesn’t make sense to think of as a universal value, but rather in contexts, like you pointed out with hate speech removal being in line with the beliefs of most people on the main Lemmy instances.
There are some concepts, for example, that I think are fine to discuss in an academic situation but should be censored in public spaces, especially when it comes to explicitly genocidal ideologies like Nazism, or bigoted hate speech.
