As just one example, not intended to be partisan: the elderly husband of the Speaker of the House was violently attacked and a sizable portion of the country either tacitly or openly endorses it. That is not a safe society. And it's very, very well-documented by now that social media in which violent / hate speech are not moderated are a key factor driving the increase in political violence and extremism. For people in positions of great power to ignore the complexity of what's happening to society, and to lean on populist (and reductive/misleading) arguments about censorship and freedom of speech for personal gain, comes across as either unintelligent or profoundly irresponsible.
Nancy, or Paul, Pelosi weren’t even engaged in any discourse on twitter with his attacker. It sounds like you’re saying in order for discourse to be safe, people with power over communication needs to regulate other people on our behalf? The big question is how do they decide? We do have some laws about direct threats, spam, fraud and negligence, but I’m not sure where your definition fits in. It seems like it is extremely difficult to get right and very easy to get wrong.
