Is there any reasonably valid speech that is unduly silenced by cancel culture? I don't disagree that people are restrictive of their speech, but I am trying to ascertain if we are better or worse off due to self-censorship.
I don't have any particularly noteworthy political opinions; most people would probably put me in the "surprisingly ordinary" box if they had to categorize me. Despite that, I wouldn't dream of getting into something like a political discussion on Twitter. It's simply impossible to know whom the mob will go after next, or in 10 or 20 years.
I don't know how many others feel the same way, but I do know there are others out there. There is a non-zero chance that one of us has something really important to say, but won't, because we don't want to face a potential angry online mob in the future.
