I don’t know. You’re the one who brought up witch burnings. I’m just as confused about it as you now appear to be.
Let's try to recap then.
Some of us take the position that "Cancel Culture" has some serious problems, is open to extreme abuse, is notoriously reactionary and allows anonymous people to punish perceived wrong-thinkers on the basis of incomplete or erroneous information, and has a high potential for crossing the line into outright extrajudicial persecution of belief. We essentially argue that, while not every single instance of "Cancel Culture" has bad outcomes, it has in many cases imposed serious hardship, suffering, and trauma on people and it allows for the "internet mob" to engage in death threats and harassment that are illegal but can't be pursued because the actors are anonymous.
Other people in this thread responded by noting that 1) "Cancel Culture" isn't new, it's been around forever and 2) Some people really deserve to be punished and have their lives ruined for transgressing social norms and 3) Some of those people came out of it okay at the end of the day so it's no big deal.
My response to 1) was to say that whether or not it's new is irrelevant, it's an activity that is wide open to abuse and presents a problem. It presented a problem when it was done in the past as well (cite McCarthyism, witch burnings, etc.). You responded with the very odd rejoinder of "well why are you suddenly worried about it now?". To which I responded that I wasn't alive when those prior things happened. It doesn't make sense for me to be "worried" about things that happened in the past and which I cannot affect in any way, whereas this is happening now, and I see in it the same patterns of behavior that have led to extremely bad outcomes in the past, so I am worried about what is happening now. This seems confusing to you, and I really don't know why.
My response to 2) is that the subjective determination that some people deserve it isn't enough. That same determination was believed to be sufficient by actors in the past who engaged in widespread persecution of belief and all sorts of atrocities. One's belief in their moral righteousness should not rationalize harassment of others who do not hold that same belief.
My response to 3) is that the eventual non-death outcome for some high-profile people doesn't offset the risk and the danger. We only get exposed to the high profile cases in the media, and many of those people can garner support and move on. But someone of lesser means might end up devastated. It's akin to arguing that because some children who were bullied managed to survive and become stronger for it, we shouldn't take a stand against bullying.
