This idea that individuals aren’t allowed to publicly criticize the actions of public figures, or report on their own experiences with public figures, is so painfully stupid that I find it astonishing that you are arguing in good faith. This is not something you would actually believe in other contexts (say, if a CEO is accused of verbal abuse).
Then maybe you should step back and consider the possibility that you are misunderstanding the point and arguing with a straw man. I never at any point said that “individuals aren’t allowed to publicly criticize the actions of public figures”, and I don’t think you’re acting in good faith by interpreting me as such.
I’m not saying the court of public opinion is the wrong venue for this sort of thing; I’m saying the court of public opinion is, by any reasonable standard, a kangaroo court, and we should exercise much more caution and skepticism toward its judgments than we exercise towards the judgments made by a court of law. Keeping this caution in mind is, in fact, what distinguishes a measured application of social/professional sanction from outright “mob justice”.
“...there is a court and criminal justice system for a reason”
John Wayne Gacy was convicted in a court via the criminal justice system. As a society, we have chosen this as our mechanism for adjudicating these types of accusations, and that mechanism has evolved certain safeguards over time. It’s not perfect, but it is a far fairer venue to be tried in than the “court of public opinion”. That’s not an insignificant point, and you’re glossing over it entirely.
