Greg Lukianoff and Talia Barnes in Persuasion:
Concern about the proliferation of hate speech motivates many who oppose the recent acquisition of Twitter by billionaire Elon Musk, who says he plans to turn the heavily moderated platform into a bastion for free speech. Sources ranging from writers at major news publications to CEOs have voiced fears that free-speech-friendly policies will make the platform a haven for “totally lawless hate, bigotry, and misogyny,” as actress Jameela Jamil put it in her farewell-to-Twitter tweet.
But those who take for granted that hate speech should be policed on Twitter would do well to learn the history of attempts to police hate speech on campuses in the United States. Some readers may be surprised to learn that American universities have attempted to regulate hate speech for four decades now: This real-world experiment has shown how subjective and nebulous restrictions chill speech in often-surprising ways.
