And see, this is really the crux of it: I think "outrage reddit" perceives "cancel culture" to be media articles bemoaning that cancel culture is a trend or some such thing. If that's all they're arguing, they can have it, because, well, who cares? Lol, that's what you're mad about? The only meaningful definition of cancel culture, as far as I'm concerned, is a set of assumptions and beliefs shared by a group of people (that is, a culture), which ultimately precipitates or justifies the cancellation of somebody's career, somewhere, sometime, in some way (anything from Sarah Silverman being cancelled for a single role for something objectionable she posted over a decade ago to Al Franken losing his entire (political) career).
These are two very separate things: the first is completely unimportant, as far as I'm concerned, and the latter is obviously real, and quite serious, and therefore not to be taken lightly no matter how rare you can prove it is in practice (in particular, because any existence at all of a cancel culture has a chilling effect on everybody who has something to lose).
