I feel like cannibalism has to be an intentional act.

Like, I happen to smell other peoples farts, but I’m not a fart sniffer.

Humans are filthy, disgusting, germ ridden animals.

No, we just microdose on each other

Not sure what you’re doing to other people, but I don’t think I’ve ingested macroscopic quantities of anyone else’s skin cells since I was a young child who was a little too fond of biting. If you count individual cells it’s probably technically true that I inhale some occasionally, but that’s a bit misleading. I’m still constantly practicing self-cannibalism though!
