This might seem odd coming from an anarchist, and free speech absolutist; but, I do think that it's safe to say that the cancel mob can easily be seen as worse than the government abridging the First Amendment.
I'm not even talking about extremes like the Charlie Hebdo shooting. I think that a lot of victims, like Justine Sacco, if given the choice, would take thirty days in jail for a bad tweet over what was inflicted upon them by the mob.
Of course, the cynic and the realist in me knows that it's absurd to believe that these victims would ever be forgiven by the woke mob. If you tell a bad joke, they really want you dead, and to live in misery until you die. Spending a few days in jail won't placate these howling banshees.
Still, the reality remains that the participants and supporters of cancel culture have no moral high ground in regard to free speech by comparison to oppressive governments.
