Mute button is the "healthy" form of cancel culture...
But of course what we think of cancel culture extends further... Campaigns to get someone fired from their job, or now in 2025 deported, etc...
It's still pretty subjective IMHO. What one person might view as an act of "cancellation" could be seen by someone else as a public service, i.e. "everyone should know that this person in a position of authority holds this view."
