I've seen "cancel culture" in analogy to the immune response for a long time now, and it fits pretty well.

If you imagine that ideas can spread like infections, it makes sense to quarantine and ostracize individuals that have caught threathening ideas.. There's also the thing where someone socializing with an 'infected' individual gets treated as if they were infected as well. Better safe than sorry.

With a high false positive rate, you err on the side of safety. Smoke detectors have a high false positive rate by design. You'd rather it go off on accident every now and then than fail when there's actually smoke. Present-day "McCarthyism" seems like a good example of this process in action.

To people who dismiss the idea of cancel culture, I say this: check out South-Korea. Celebrities are regularly driven to suicide by online mobs. It's an epidemic. If a slight moral flaw is perceived, they're fair game. And the mobs can be brutal.
