you could probably successfully argue that even herbivores are inflicting violence on plants because they’re destroying and consuming an organism.
Don’t need to stretch that far.
Lots of herbivores use violence, either in defense against predators or in competition with their own species for territory, resources, or mates. I’d even go as far as to say that the majority of them do, at least for the first of those two purposes – it’s rare to find an herbivore so passive that it wouldn’t use ‘violence’ to protect itself against a predator attack if necessary.
